+To utilise plugins that have been created by users within the [Netbox Community](https://github.com/netbox-community/netbox/wiki/Plugins) a custom image must be used. 
+
+Lets start with a fresh install of netbox-docker.
+
+* `git clone -b release https://github.com/netbox-community/netbox-docker.git`
+* Change `/env/netbox.env` to your required settings.
+* Create a few files these are (`plugin_requirements.txt`, `Dockerfile-Plugins`, `docker-compose.override.yml`)
+
+## Python Requirements
+The `plugin_requirements.txt` file needs to contain all the plugins that are required. 
+```
+ntc-netbox-plugin-onboarding
+```
+> NOTE: These must be on PyPi to work.
+
+## Netbox Configuration
+
+To get plugins to work within Netbox you need to add some configuration to `configuration.py`.
+```
+PLUGINS = ["netbox_onboarding"]
+
+# PLUGINS_CONFIG = {
+#   "netbox_onboarding": {
+#     ADD YOUR SETTINGS HERE
+#   }
+# }
+```
+> NOTE: This can differ for every plugin. To learn more about this see the [Netbox documentation](https://netbox.readthedocs.io/en/stable/plugins/#enable-the-plugin).
+
+## Custom Docker File
+
+The new `Dockerfile-Plugins` will enable us to build a new image with the required plugins installed. 
+```
+FROM netboxcommunity/netbox:latest
+
+copy ./plugin_requirements.txt /
+RUN pip install  --no-warn-script-location -r /plugin_requirements.txt
+```
+> NOTE: You can swap the image out to use any of the images that the Netbox-Docker community publishes to [Docker Hub](https://hub.docker.com/r/netboxcommunity/netbox/tags). For example if LDAP is required, swap out `netboxcommunity/netbox:latest` for `netboxcommunity/netbox:latest-ldap`.
+
+## Docker Compose Override
+
+`docker-compose.override.yml`, as its name implies, can contain configuration overrides for existing services or entirely new services.
+```
+version: '3.4'
+services:
+  nginx:
+    ports:
+      - 8000:8080
+  netbox:
+    build:
+      context: .
+      dockerfile: Dockerfile-Plugins
+    image: netbox:latest-plugins
+  netbox-worker:
+    image: netbox:latest-plugins
+```
+This configuration will change the ports `NGINX` will use. It will also select the build file created in previous steps and tell the `netbox-worker` service to now use the new image (netbox:latest-plugins) that has been created. 
+
+## Build and Deploy
+To build and deploy this in docker two commands are required.
+```
+docker-compose build --no-cache
+docker-compose up -d
+```
