##### GENERAL CONFIG ######
###########################

# String. Log level to use throughout the application. Must be lower-case.
# Options: ["trace","debug","info","warn","error","fatal"]
# Default: "info"
log-level: "info"

# Bool. Log database queries when log-level is set to debug or trace.
# This setting produces verbose logs, so it's better to only enable it
# when you're trying to track an issue down.
# Options: [true, false]
# Default: false
log-db-queries: false

# Bool. Include the client IP in the emitted log lines
# Options: [true, false]
# Default: true
log-client-ip: true

# String. Format to use for the timestamp in log lines.
# If set to the empty string, the timestamp will be
# ommitted from the logs entirely.
#
# The format must be compatible with Go's time.Layout, as
# documented on https://pkg.go.dev/time#pkg-constants.
#
# Examples: ["2006-01-02T15:04:05.000Z07:00", ""]
# Default: "02/01/2006 15:04:05.000"
log-timestamp-format: "02/01/2006 15:04:05.000"

# String. Application name to use internally.
# Examples: ["My Application","gotosocial"]
# Default: "gotosocial"
application-name: "gotosocial"

# String. The user that will be shown instead of the landing page. if no user is set, the landing page will be shown.
# Examples: "admin"
# Default: ""
landing-page-user: ""

# String. Hostname that this server will be reachable at. Defaults to localhost for local testing,
# but you should *definitely* change this when running for real, or your server won't work at all.
# DO NOT change this after your server has already run once, or you will break things!
# Examples: ["gts.example.org","some.server.com"]
# Default: "localhost"
host: "localhost"

# String. Domain to use when federating profiles. This is useful when you want your server to be at
# eg., "gts.example.org", but you want the domain on accounts to be "example.org" because it looks better
# or is just shorter/easier to remember.
#
# To make this setting work properly, you need to redirect requests at "example.org/.well-known/webfinger"
# to "gts.example.org/.well-known/webfinger" so that GtS can handle them properly.
#
# You should also redirect requests at "example.org/.well-known/nodeinfo" in the same way.
#
# You should also redirect requests at "example.org/.well-known/host-meta" in the same way. This endpoint
# is used by a number of clients to discover the API endpoint to use when the host and account domain are
# different.
#
# An empty string (ie., not set) means that the same value as 'host' will be used.
#
# DO NOT change this after your server has already run once, or you will break things!
#
# Please read the appropriate section of the installation guide before you go messing around with this setting:
# https://docs.gotosocial.org/en/latest/advanced/host-account-domain/
#
# Examples: ["example.org","server.com"]
# Default: ""
account-domain: ""

# String. Protocol to use for the server. Only change to http for local testing!
# This should be the protocol part of the URI that your server is actually reachable on. So even if you're
# running GoToSocial behind a reverse proxy that handles SSL certificates for you, instead of using built-in
# letsencrypt, it should still be https.
# Options: ["http","https"]
# Default: "https"
protocol: "https"

# String. Address to bind the GoToSocial server to.
# This can be an IPv4 address or an IPv6 address (surrounded in square brackets), or a hostname.
# The default value will bind to all interfaces, which makes the server
# accessible by other machines. For most setups there is no need to change this.
# If you are using GoToSocial in a reverse proxy setup with the proxy running on
# the same machine, you will want to set this to "localhost" or an equivalent,
# so that the proxy can't be bypassed.
# Examples: ["0.0.0.0", "172.128.0.16", "localhost", "[::]", "[2001:db8::fed1]"]
# Default: "0.0.0.0"
bind-address: "0.0.0.0"

# Int. Listen port for the GoToSocial webserver + API. If you're running behind a reverse proxy and/or in a docker,
# container, just set this to whatever you like (or leave the default), and make sure it's forwarded properly.
# If you are running with built-in letsencrypt enabled, and running GoToSocial directly on a host machine, you will
# probably want to set this to 443 (standard https port), unless you have other services already using that port.
# This *MUST NOT* be the same as the letsencrypt port specified below, unless letsencrypt is turned off.
# Examples: [443, 6666, 8080]
# Default: 8080
port: 8080

# Array of string. CIDRs or IP addresses of proxies that should be trusted when determining real client IP from behind a reverse proxy.
# If you're running inside a Docker container behind Traefik or Nginx, for example, add the subnet of your docker network,
# or the gateway of the docker network, and/or the address of the reverse proxy (if it's not running on the host network).
# Example: ["127.0.0.1/32", "172.20.0.1"]
# Default: ["127.0.0.1/32", "::1"] (localhost ipv4 + ipv6)
trusted-proxies:
  - "127.0.0.1/32"
  - "::1"

############################
##### DATABASE CONFIG ######
############################

# Config pertaining to the Gotosocial database connection

# String. Database type.
# Options: ["postgres","sqlite"]
# Default: "postgres"
db-type: "postgres"

# String. Database address or parameters.
#
# For Postgres, this should be the address or socket at which the database can be reached.
#
# For Sqlite, this should be the path to your sqlite database file. Eg., /opt/gotosocial/sqlite.db.
# If the file doesn't exist at the specified path, it will be created.
# If just a filename is provided (no directory) then the database will be created in the same directory
# as the GoToSocial binary.
# If address is set to :memory: then an in-memory database will be used (no file).
# WARNING: :memory: should NOT BE USED except for testing purposes.
#
# Examples: ["localhost","my.db.host","127.0.0.1","192.111.39.110",":memory:", "sqlite.db"]
# Default: ""
db-address: ""

# Int. Port for database connection.
# Examples: [5432, 1234, 6969]
# Default: 5432
db-port: 5432

# String. Username for the database connection.
# Examples: ["mydbuser","postgres","gotosocial"]
# Default: ""
db-user: ""

# String. Password to use for the database connection
# Examples: ["password123","verysafepassword","postgres"]
# Default: ""
db-password: ""

# String. Name of the database to use within the provided database type.
# Examples: ["mydb","postgres","gotosocial"]
# Default: "gotosocial"
db-database: "gotosocial"

# String. Disable, enable, or require SSL/TLS connection to the database.
# If "disable" then no TLS connection will be attempted.
# If "enable" then TLS will be tried, but the database certificate won't be checked (for self-signed certs).
# If "require" then TLS will be required to make a connection, and a valid certificate must be presented.
# Options: ["disable", "enable", "require"]
# Default: "disable"
db-tls-mode: "disable"

# String. Path to a CA certificate on the host machine for db certificate validation.
# If this is left empty, just the host certificates will be used.
# If filled in, the certificate will be loaded and added to host certificates.
# Examples: ["/path/to/some/cert.crt"]
# Default: ""
db-tls-ca-cert: ""

# Int. Number to multiply by CPU count to set permitted total of open database connections (in-use and idle).
# You can use this setting to tune your database connection behavior, though most admins won't need to touch it.
#
# Example values for multiplier 8:
#
# 1 cpu = 08 open connections
# 2 cpu = 16 open connections
# 4 cpu = 32 open connections
#
# Example values for multiplier 4:
#
# 1 cpu = 04 open connections
# 2 cpu = 08 open connections
# 4 cpu = 16 open connections
#
# A multiplier of 8 is a sensible default, but you may wish to increase this for instances
# running on very performant hardware, or decrease it for instances using v. slow CPUs.
#
# If you set the multiplier to less than 1, only one open connection will be used regardless of cpu count.
#
# Examples: [16, 8, 10, 2]
# Default: 8
db-max-open-conns-multiplier: 8

# String. SQLite journaling mode.
# SQLite only -- unused otherwise.
# If set to empty string, the sqlite default will be used.
# See: https://www.sqlite.org/pragma.html#pragma_journal_mode
# Examples: ["DELETE", "TRUNCATE", "PERSIST", "MEMORY", "WAL", "OFF"]
# Default: "WAL"
db-sqlite-journal-mode: "WAL"

# String. SQLite synchronous mode.
# SQLite only -- unused otherwise.
# If set to empty string, the sqlite default will be used.
# See: https://www.sqlite.org/pragma.html#pragma_synchronous
# Examples: ["OFF", "NORMAL", "FULL", "EXTRA"]
# Default: "NORMAL"
db-sqlite-synchronous: "NORMAL"

# Byte size. SQlite cache size.
# SQLite only -- unused otherwise.
# If set to empty string or zero, the sqlite default (2MiB) will be used.
# See: https://www.sqlite.org/pragma.html#pragma_cache_size
#
# More is not necessarily better for caches. They need to be tuned to the
# workload. The defaults should be plenty for most instances and you shouldn't
# change it. If you do change it, ensure you mention this when requesting help
# in the GoToSocial Help channel.
#
# Examples: ["0", "2MiB", "8MiB", "64MiB"]
# Default: "8MiB"
db-sqlite-cache-size: "8MiB"

# Duration. SQlite busy timeout.
# SQLite only -- unused otherwise.
# If set to empty string or zero, the sqlite default will be used.
# See: https://www.sqlite.org/pragma.html#pragma_busy_timeout
# Examples: ["0s", "1s", "30s", "1m", "5m"]
# Default: "30m"
db-sqlite-busy-timeout: "30m"

cache:
  # cache.memory-target sets a target limit that
  # the application will try to keep it's caches
  # within. This is based on estimated sizes of
  # in-memory objects, and so NOT AT ALL EXACT.
  # Examples: ["100MiB", "200MiB", "500MiB", "1GiB"]
  # Default: "100MiB"
  memory-target: "100MiB"

######################
##### WEB CONFIG #####
######################

# Config pertaining to templating and serving of web pages/email notifications and the like

# String. Directory from which gotosocial will attempt to load html templates (.tmpl files).
# Examples: ["/some/absolute/path/", "./relative/path/", "../../some/weird/path/"]
# Default: "./web/template/"
web-template-base-dir: "./web/template/"

# String. Directory from which gotosocial will attempt to serve static web assets (images, scripts).
# Examples: ["/some/absolute/path/", "./relative/path/", "../../some/weird/path/"]
# Default: "./web/assets/"
web-asset-base-dir: "./web/assets/"

###########################
##### INSTANCE CONFIG #####
###########################

# Config pertaining to instance federation settings, pages to hide/expose, etc.

# Array of string. BCP47 language tags to indicate preferred languages of users on this instance.
#
# If you provide these, you should provide these in order from most-preferred to least-preferred,
# but note that leaving out a language from this array doesn't mean it can't be used on this instance,
# it only means it won't be advertised as a preferred instance language.
#
# It is valid to provide no entries here; your instance will then have no particular preferred language.
#
# See here for commonly-used tags: https://en.wikipedia.org/wiki/IETF_language_tag#List_of_common_primary_language_subtags
# See here for all current tags: https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry
#
# Example: ["nl", "en-gb", "fr"]
# Default: []
instance-languages: []

# String. Federation mode to use for this instance.
#
# "blocklist" -- open federation by default. Only instances that are explicitly
#                blocked will be denied (unless they are also explicitly allowed).
#
# "allowlist" -- closed federation by default. Only instances that are explicitly
#                allowed will be able to interact with this instance.
#
# For more details on blocklist and allowlist modes, check the documentation at:
# https://docs.gotosocial.org/en/latest/admin/federation_modes
#
# Options: ["blocklist", "allowlist"]
# Default: "blocklist"
instance-federation-mode: "blocklist"

# Bool. Enable spam filtering heuristics for messages entering your instance
# via the federation API. Regardless of what you set here, basic checks
# for message relevancy will still be performed, but you can try enabling
# this setting if you are being spammed with unwanted messages from other
# instances, and want to more strictly filter out spam messages.
#
# THIS IS CURRENTLY AN EXPERIMENTAL SETTING, AND MAY FILTER OUT LEGITIMATE
# MESSAGES, OR FAIL TO FILTER OUT SPAMMY MESSAGES. It is recommended to
# only enable this setting when the fediverse is in the midst of a spam
# wave, and you need to batten down the hatches to keep your instance usable.
#
# The decision of whether a message counts as spam or not is made based on
# the following heuristics, in order, where receiver = the account on your
# instance that received a message in their inbox, and requester = the
# account on a remote instance that sent the message.
#
# First, basic relevancy checks
#
#  1. Receiver follows requester. Return OK.
#  2. Statusable doesn't mention receiver. Return NotRelevant.
#
# If instance-federation-spam-filter = false, then return OK now.
# Otherwise check:
#
#  3. Receiver is locked and is followed by requester. Return OK.
#  4. Five or more people are mentioned. Return Spam.
#  5. Receiver follow (requests) a mentioned account. Return OK.
#  6. Statusable has a media attachment. Return Spam.
#  7. Statusable contains non-mention, non-hashtag links. Return Spam.
#
# Messages identified as spam will be dropped from your instance, and not
# inserted into the database, or into home timelines or notifications.
#
# Options: [true, false]
# Default: false
instance-federation-spam-filter: false

# Bool. Allow unauthenticated users to make queries to /api/v1/instance/peers?filter=open in order
# to see a list of instances that this instance 'peers' with. Even if set to 'false', then authenticated
# users (members of the instance) will still be able to query the endpoint.
# Options: [true, false]
# Default: false
instance-expose-peers: false

# Bool. Allow unauthenticated users to make queries to /api/v1/instance/peers?filter=suspended in order
# to see a list of instances that this instance blocks/suspends. Even if set to 'false', then authenticated
# users (members of the instance) will still be able to query the endpoint.
#
# WARNING: Setting this variable to 'true' may result in your instance being scraped by blocklist scrapers.
# See: https://docs.gotosocial.org/en/latest/admin/domain_blocks/#block-announce-bots
#
# Options: [true, false]
# Default: false
instance-expose-suspended: false

# Bool. Allow unauthenticated users to view /about/suspended,
# showing the HTML rendered list of instances that this instance blocks/suspends.
# Options: [true, false]
# Default: false
instance-expose-suspended-web: false

# Bool. Allow unauthenticated users to make queries to /api/v1/timelines/public in order
# to see a list of public posts on this server. Even if set to 'false', then authenticated
# users (members of the instance) will still be able to query the endpoint.
# Options: [true, false]
# Default: false
instance-expose-public-timeline: false

# Bool. This flag tweaks whether GoToSocial will deliver ActivityPub messages
# to the shared inbox of a recipient, if one is available, instead of delivering
# each message to each actor who should receive a message individually.
#
# Shared inbox delivery can significantly reduce network load when delivering
# to multiple recipients share an inbox (eg., on large Mastodon instances).
#
# See: https://www.w3.org/TR/activitypub/#shared-inbox-delivery
#
# Options: [true, false]
# Default: true
instance-deliver-to-shared-inboxes: true

# Bool. This flag will inject a Mastodon version into the version field that
# is included in /api/v1/instance. This version is often used by Mastodon clients
# to do API feature detection. By injecting a Mastodon compatible version, it is
# possible to cajole those clients to behave correctly with GoToSocial.
#
# Options: [true, false]
# Default: false
instance-inject-mastodon-version: false


###########################
##### ACCOUNTS CONFIG #####
###########################

# Config pertaining to creation and maintenance of accounts on the server, as well as defaults for new accounts.

# Bool. Allow people to submit new sign-up / registration requests via the form at /signup.
#
# Options: [true, false]
# Default: false
accounts-registration-open: false

# Bool. Are sign up requests required to submit a reason for the request (eg., an explanation of why they want to join the instance)?
# Options: [true, false]
# Default: true
accounts-reason-required: true

# Bool. Allow accounts on this instance to set custom CSS for their profile pages and statuses.
# Enabling this setting will allow accounts to upload custom CSS via the /user settings page,
# which will then be rendered on the web view of the account's profile and statuses.
#
# For instances with public sign ups, it is **HIGHLY RECOMMENDED** to leave this setting on 'false',
# since setting it to true allows malicious accounts to make their profile pages misleading, unusable
# or even dangerous to visitors. In other words, you should only enable this setting if you trust
# the users on your instance not to produce harmful CSS.
#
# Regardless of what this value is set to, any uploaded CSS will not be federated to other instances,
# it will only be shown on profiles and statuses on *this* instance.
#
# Options: [true, false]
# Default: false
accounts-allow-custom-css: false

# Int. If accounts-allow-custom-css is true, this is the permitted length in characters for
# CSS uploaded by accounts on this instance. No effect if accounts-allow-custom-css is false.
#
# Examples: [500, 5000, 9999]
# Default: 10000
accounts-custom-css-length: 10000

########################
##### MEDIA CONFIG #####
########################

# Config pertaining to media uploads (videos, image, image descriptions, emoji).

# Size. Maximum allowed image upload size in bytes.
#
# Raising this limit may cause other servers to not fetch media
# attached to a post.
#
# Examples: [2097152, 10485760, 10MB, 10MiB]
# Default: 10MiB (10485760 bytes)
media-image-max-size: 10MiB

# Size. Maximum allowed video upload size in bytes.
#
# Raising this limit may cause other servers to not fetch media
# attached to a post.
#
# Examples: [2097152, 10485760, 40MB, 40MiB]
# Default: 40MiB (41943040 bytes)
media-video-max-size: 40MiB

# Int. Minimum amount of characters required as an image or video description.
# Examples: [500, 1000, 1500]
# Default: 0 (not required)
media-description-min-chars: 0

# Int. Maximum amount of characters permitted in an image or video description.
# Examples: [1000, 1500, 3000]
# Default: 1500
media-description-max-chars: 1500

# Size. Max size in bytes of emojis uploaded to this instance via the admin API.
#
# The default is the same as the Mastodon size limit for emojis (50kb), which allows
# for good interoperability. Raising this limit may cause issues with federation
# of your emojis to other instances, so beware.
#
# Examples: [51200, 102400, 50KB, 50KiB]
# Default: 50KiB (51200 bytes)
media-emoji-local-max-size: 50KiB

# Size. Max size in bytes of emojis to download from other instances.
#
# By default this is 100kb, or twice the size of the default for media-emoji-local-max-size.
# This strikes a good balance between decent interoperability with instances that have
# higher emoji size limits, and not taking up too much space in storage.
#
# Examples: [51200, 102400, 100KB, 100KiB]
# Default: 100KiB (102400 bytes)
media-emoji-remote-max-size: 100KiB

# The below media cleanup settings allow admins to customize when and
# how often media cleanup + prune jobs run, while being set to a fairly
# sensible default (every night @ midnight). For more information on exactly
# what these settings do, with some customization examples, see the docs:
# https://docs.gotosocial.org/en/latest/admin/media_caching#cleanup

# Int. Number of days to cache media from remote instances before
# they are removed from the cache. When remote media is removed from
# the cache, it is deleted from storage but the database entries for
# the media are kept so that it can be fetched again if requested by a user.
#
# If this is set to 0, then media from remote instances will be cached indefinitely.
#
# Examples: [30, 60, 7, 0]
# Default: 7
media-remote-cache-days: 7

# String. 24hr time of day formatted as hh:mm.
# Examples: ["14:30", "00:00", "04:00"]
# Default: "00:00" (midnight).
media-cleanup-from: "00:00"

# Duration. Period between media cleanup runs.
# More than once per 24h is not recommended
# is likely overkill. Setting this to something
# very low like once every 10 minutes will probably
# cause lag and possibly other issues.
# Examples: ["24h", "72h", "12h"]
# Default: "24h" (once per day).
media-cleanup-every: "24h"

##########################
##### STORAGE CONFIG #####
##########################

# Config pertaining to storage of user-created uploads (videos, images, etc).

# String. Type of storage backend to use.
# Examples: ["local", "s3"]
# Default: "local" (storage on local disk)
storage-backend: "local"

# String. Directory to use as a base path for storing files.
# Make sure whatever user/group gotosocial is running as has permission to access
# this directory, and create new subdirectories and files within it.

# Only required when running with the s3 storage backend.
# Examples: ["minio:9000", "s3.nl-ams.scw.cloud", "s3.us-west-002.backblazeb2.com"]
# GoToSocial uses "DNS-style" when accessing buckets.
# If you are using Scaleways object storage, please remove the "bucket name" from the endpoint address
# Default: ""
storage-s3-endpoint: ""

# Bool. If data stored in S3 should be proxied through GoToSocial instead of redirecting to a presigned URL.
#
# Default: false
storage-s3-proxy: false

# Bool. Use SSL for S3 connections.
#
# Only set this to 'false' when testing locally.
#
# Default: true
storage-s3-use-ssl: true

# String. Access key part of the S3 credentials.
# Consider setting this value using environment variables to avoid leaking it via the config file
# Only required when running with the s3 storage backend.
# Examples: ["AKIAJSIE27KKMHXI3BJQ","miniouser"]
# Default: ""
storage-s3-access-key: ""

# String. Secret key part of the S3 credentials.
# Consider setting this value using environment variables to avoid leaking it via the config file
# Only required when running with the s3 storage backend.
# Examples: ["5bEYu26084qjSFyclM/f2pz4gviSfoOg+mFwBH39","miniopassword"]
# Default: ""
storage-s3-secret-key: ""

# String. Name of the storage bucket.
#
# If you have already encoded your bucket name in the storage-s3-endpoint, this
# value will be used as a directory containing your data.
#
# The bucket must exist prior to starting GoToSocial
#
# Only required when running with the s3 storage backend.
# Examples: ["gts","cool-instance"]
# Default: ""
storage-s3-bucket: ""

###########################
##### STATUSES CONFIG #####
###########################

# Config pertaining to the creation of statuses/posts, and permitted limits.

# Int. Maximum amount of characters permitted for a new status,
# including the content warning (if set).
#
# Note that going way higher than the default might break federation.
#
# Examples: [140, 500, 5000]
# Default: 5000
statuses-max-chars: 5000

# Int. Maximum amount of options to permit when creating a new poll.
# Note that going way higher than the default might break federation.
# Examples: [4, 6, 10]

##############################
##### LETSENCRYPT CONFIG #####
##############################

# Config pertaining to the automatic acquisition and use of LetsEncrypt HTTPS certificates.

# Bool. Whether or not letsencrypt should be enabled for the server.
# If false, the rest of the settings here will be ignored.
# If you serve GoToSocial behind a reverse proxy like nginx or traefik, leave this turned off.
# If you don't, then turn it on so that you can use https.
# Options: [true, false]
# Default: false
letsencrypt-enabled: false

# Int. Port to listen for letsencrypt certificate challenges on.
# If letsencrypt is enabled, this port must be reachable or you won't be able to obtain certs.
# If letsencrypt is disabled, this port will not be used.
# This *must not* be the same as the webserver/API port specified above.
# Examples: [80, 8000, 1312]
# Default: 80
letsencrypt-port: 80

# String. Directory in which to store LetsEncrypt certificates.
# It is a good move to make this a sub-path within your storage directory, as it makes
# backup easier, but you might wish to move them elsewhere if they're also accessed by other services.
# In any case, make sure GoToSocial has permissions to write to / read from this directory.
# Examples: ["/home/gotosocial/storage/certs", "/acmecerts"]
# Default: "/gotosocial/storage/certs"
letsencrypt-cert-dir: "/gotosocial/storage/certs"

# internal oauth flow will be used, where users sign in to GtS with username/password.
# Options: [true, false]
# Default: false
oidc-enabled: false

# String. Name of the oidc idp (identity provider). This will be shown to users when
# they log in.

# Default: ""
oidc-client-secret: ""

# Array of string. Scopes to request from the OIDC provider. The returned values will be used to
# populate users created in GtS as a result of the authentication flow. 'openid' and 'email' are required.
# 'profile' is used to extract a username for the newly created user.
# 'groups' is optional and can be used to determine if a user is an admin based on oidc-admin-groups.
# Examples: See eg., https://auth0.com/docs/scopes/openid-connect-scopes
# Default: ["openid", "email", "profile", "groups"]
oidc-scopes:
  - "openid"
  - "email"
  - "profile"
  - "groups"

# Bool. Link OIDC authenticated users to existing ones based on their email address.
# This is mostly intended for migration purposes if you were running previous versions of GTS
# which only correlated users with their email address. Should be set to false for most usecases.
# Options: [true, false]
# Default: false
oidc-link-existing: false

# Array of string. If the returned ID token contains a 'groups' claim that matches one of the
# groups in oidc-allowed-groups, then this user will be granted access on the GtS instance. If the array is empty,
# then all groups will be granted permission.
# Default: []

# will be included in the To field, so that each recipient can see who else got the
# email, and they can 'reply all' to the other recipients if they want to.
#
# If false, email will be sent to Undisclosed Recipients, and each recipient will not
# be able to see who else received the email.
#
# It might be useful to change this setting to 'true' if you want to be able to discuss
# new moderation reports with other admins by 'replying-all' to the notification email.
# Default: false

################################
##### HTTP CLIENT SETTINGS #####
################################

# Settings for OUTGOING http client connections used by GoToSocial to make
# requests to remote resources (status GETs, media GETs, inbox POSTs, etc).

http-client:

  # Duration. Timeout to use for outgoing HTTP requests. If the timeout
  # is exceeded, the connection to the remote server will be dropped.
  # A value of 0s indicates no timeout: this is not advised!
  # Examples: ["5s", "10s", "0s"]
  # Default: "10s"
  timeout: "10s"

  ########################################
  #### RESERVED IP RANGE EXCEPTIONS ######
  ########################################
  #
  # Explicitly allow or block outgoing dialing within the provided IPv4/v6 CIDR ranges.
  #
  # By default, as a basic security precaution, GoToSocial blocks outgoing dialing within most "special-purpose"
  # IP ranges. However, it may be desirable for admins with more exotic setups (proxies, funky NAT, etc) to
  # explicitly override one or more of these otherwise blocked ranges.
  #
  # Each of the below allow/block config options accepts an array of IPv4 and/or IPv6 CIDR strings.
  # For example, to override the hardcoded block of IPv4 and IPv6 dialing to localhost, set:
  #
  #   allow-ips: ["127.0.0.1/32", "::1/128"].
  #
  # You can also use YAML multi-line arrays to define these, but be diligent with indentation.
  #
  # When dialing, GoToSocial will first check if the destination falls within explicitly allowed IP ranges,
  # then explicitly blocked IP ranges, then the default (hardcoded) blocked IP ranges, returning OK on the
  # first allowed match, not OK on the first blocked match, or just defaulting to OK if nothing is matched.
  #
  # As with all security settings, it is better to start too restrictive and then ease off depending on
  # your use case, than to start too permissive and try to close the stable door after the horse has
  # already bolted. With this in mind:
  # - Don't touch these settings unless you have a good reason to, and only if you know what you're doing.
  # - When adding explicitly allowed exceptions, use the narrowest possible CIDR for your use case.
  #
  # For reserved / special ranges, see:
  # - https://www.iana.org/assignments/iana-ipv4-special-registry/iana-ipv4-special-registry.xhtml
  # - https://www.iana.org/assignments/iana-ipv6-special-registry/iana-ipv6-special-registry.xhtml
  #
  # Both allow-ips and block-ips default to an empty array.
  allow-ips: []
  block-ips: []

  # Bool. Disable verification of TLS certificates of remote servers.
  # With this set to 'true', GoToSocial will not error when a remote
  # server presents an invalid or self-signed certificate.
  #
  # THIS SETTING SHOULD BE USED FOR TESTING ONLY! IF YOU TURN THIS
  # ON WHILE RUNNING IN PRODUCTION YOU ARE LEAVING YOUR SERVER WIDE
  # OPEN TO MAN IN THE MIDDLE ATTACKS! DO NOT CHANGE THIS SETTING
  # UNLESS YOU KNOW EXACTLY WHAT YOU'RE DOING AND WHY YOU'RE DOING IT.
  #
  # Default: false
  tls-insecure-skip-verify: false

#############################
##### ADVANCED SETTINGS #####
#############################

# Advanced settings pertaining to http timeouts, security, cookies, and more.
#
# ONLY ADJUST THESE SETTINGS IF YOU KNOW WHAT YOU ARE DOING!
#
# Most users will not need to (and should not) touch these settings, since
# they are set to sensible defaults, and may break if they are changed.
#
# Nevertheless, they are provided for the sake of allowing server admins to
# tweak their instance for performance or security reasons.

# String. Value of the SameSite attribute of cookies set by GoToSocial.
# Defaults to 'lax' to ensure that the OIDC flow does not break, which is
# fine in most cases. If you want to harden your instance against CSRF attacks
# and don't mind if some login-related things might break, you can set this
# to 'strict' instead.
#
# For an overview of what this does, see:
# https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie/SameSite
#
# Options: ["lax", "strict"]
# Default: "lax"
advanced-cookies-samesite: "lax"

# Int. Amount of requests to permit per router grouping from a single IP address within
# a span of 5 minutes. If this amount is exceeded, a 429 HTTP error code will be returned.
#
# If you find yourself adjusting this limit because it's regularly being exceeded,
# you should first verify that your settings for `trusted-proxies` (above) are correct.
# In many cases, when the rate limit is exceeded it is because your instance sees all
# incoming requests as coming from the *same IP address* (you can verify this by looking
# at the client IPs in your instance logs). If this is the case, try adding that IP
# address to your `trusted-proxies` *BEFORE* you go adjusting this rate limit setting!
#
# If you set this to 0 or less, rate limiting will be disabled entirely.
#
# Examples: [1000, 500, 0]
# Default: 300
advanced-rate-limit-requests: 300

# Array of string. CIDRs to except from rate limit restrictions.
# Any IPs inside the CIDR range(s) will not have rate limiting
# applied on their requests, and rate limit headers will not be
# set for those requests.
#
# For IPv6, we only take subnets up to a /64 into account. If you
# want to open up a larger prefix, you'll need to list multiple
# prefixes instead.
#
# This can be useful in the following example cases (and probably
# a bunch of others as well):
#
# 1. You've set up an automated service that uses the API, and
#    it keeps getting rate limited, even though you trust it's
#    not abusing the instance.
#
# 2. You live with multiple people who use the same instance,
#    and you're all using the same router/NAT, so you all have
#    the same IP address, and you keep rate limiting each other.
#
# 3. You mostly use your own home internet to access your instance,
#    and you want to exempt your home internet from rate limiting.
#
# You should be careful when adjusting this setting, since you
# might inadvertently make rate limiting useless if you set too
# wide a range. If in doubt, be too restrictive rather than too
# lenient, and adjust as you go.
#
# Example: ["192.168.0.0/16", "2001:DB8:FACE:CAFE::/64"]
# Default: []
advanced-rate-limit-exceptions: []

# Int. Amount of open requests to permit per CPU, per router grouping, before applying http
# request throttling. Any requests beyond the calculated limit are held in a backlog queue for
# up to 30 seconds before either being processed or timing out. Requests that don't fit in the backlog
# queue will have status 503 returned to them, and the header 'Retry-After' will be set to 30 seconds.
#
# Open request limit is available CPUs * multiplier; backlog queue limit is limit * multiplier.
#
# Example values for multiplier 8:
#
# 1 cpu = 08 open, 064 backlog
# 2 cpu = 16 open, 128 backlog
# 4 cpu = 32 open, 256 backlog
#
# Example values for multiplier 4:
#
# 1 cpu = 04 open, 016 backlog
# 2 cpu = 08 open, 032 backlog
# 4 cpu = 16 open, 064 backlog
#
# A multiplier of 8 is a sensible default, but you may wish to increase this for instances
# running on very performant hardware, or decrease it for instances using v. slow CPUs.
#
# If you set this to 0 or less, http request throttling will be disabled entirely.
#
# Examples: [8, 4, 9, 0]
# Default: 8
advanced-throttling-multiplier: 8

# Duration. Time period to use as the "retry-after" header value in response to throttled requests.
# Minimum resolution is 1 second.
#
# Examples: [30s, 10s, 5s, 1m]
# Default: "30s"
advanced-throttling-retry-after: "30s"

# Int. CPU multiplier for the fixed number of goroutines to spawn in order to send messages via ActivityPub.
# Messages will be batched and pushed to a singular queue, from which multiplier * CPU count goroutines will
# pull and attempt deliveries. This can be tuned to limit concurrent posting to remote inboxes, preventing
# your instance CPU usage skyrocketing when accounts with many followers post statuses.
#
# If you set this to 0 or less, only 1 sender will be used regardless of CPU count. This may be
# useful in cases where you are working with very tight network or CPU constraints.
#
# Example values for multiplier 2 (default):
#
# 1 cpu = 2 concurrent senders
# 2 cpu = 4 concurrent senders
# 4 cpu = 8 concurrent senders
#
# Example values for multiplier 4:
#
# 1 cpu = 4 concurrent senders
# 2 cpu = 8 concurrent senders
# 4 cpu = 16 concurrent senders
#
# Example values for multiplier <1:
#
# 1 cpu = 1 concurrent sender
# 2 cpu = 1 concurrent sender
# 4 cpu = 1 concurrent sender
advanced-sender-multiplier: 2

# Array of string. Extra URIs to add to 'img-src' and 'media-src'
# when building the Content-Security-Policy header for your instance.
#
# This can be used to allow the browser to load resources from additional
# sources like S3 buckets and so on when viewing your instance's pages
# and profiles in the browser.
#
# Since non-proxying S3 storage will be probed on instance launch to
# generate a correct Content-Security-Policy, you probably won't need
# to ever touch this setting, but it's included in the 'spirit of more
# configurable (usually) means more good'.
#
# See: https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP
#
# Example: ["s3.example.org", "some-bucket-name.s3.example.org"]
# Default: []
advanced-csp-extra-uris: []

# String. HTTP request header filtering mode to use for this instance.
#
# "block" -- only requests that are explicitly blocked by header filters
#            will be denied (unless they are also explicitly allowed).
#
# "allow" -- only requests that are explicitly allowed by header filters
#            will be accepted (unless they are also explicitly blocked).
#            This mode is considered experimental and will almost certainly
#            break access to your instance unless you are very careful.
