-## Goal
-
-Proxy a reserved public subdomain to a backend target with an always-on Linux system service.
-
-## How it Works
-
-The `zrok-share` package creates a `zrok-share.service` unit in systemd. The administrator edits the service's configuration file to specify the:
-
-1. zrok environment enable token
-1. target URL or files to be shared and backend mode, e.g. `proxy`
-1. authentication options, if wanted
-
-When the service starts it will:
-
-1. enable the zrok environment unless `/var/lib/zrok-share/.zrok/environment.json` exists
-1. reserve a public subdomain for the service unless `/var/lib/zrok-share/.zrok/reserved.json` exists
-1. start sharing the target specified as `ZROK_TARGET` in the environment file
-
 ## Installation
 
-1. Set up `zrok`'s Linux package repository by following [the Linux install guide](/guides/install/linux.mdx#install-zrok-from-the-repository), or run this one-liner to complete the repo setup and install packages.
+<LinuxShareInstall />
-
-    ```bash
-    curl -sSLf https://get.openziti.io/install.bash \
-    | sudo bash -s zrok-share
-    ```
-
-1. If you set up the repository by following the guide, then also install the `zrok-share` package. This package provides the systemd service.
-
-    ```bash title="Ubuntu, Debian"
-    sudo apt install zrok-share
-    ```
-
-    ```bash title="Fedora, Rocky"
-    sudo dnf install zrok-share

+
+## Overview
+
+You can run any number of zrok share services as `systemd --user` units with your Linux user's zrok environment in `~/.zrok`. This is like [zrok frontdoor](/guides/frontdoor.mdx) except that frontdoor is a system service managed by root separately from your user's login. Linux user shares, Linux system services, and Docker shares all use the same configuration environment variables.
+
+## Install the Linux Package
+
+The package provides the `zrok` executable and service unit template.
+
+<LinuxShareInstall />
+
+## Create a User Share Configuration File
+
+Substitute a name for your instance in place of `my-instance` in the following example. To avoid character escaping problems, use only letters, numbers, hyphens, and underscores in the instance name, not spaces or other special characters.
+
+```bash
+ZROK_INSTANCE="my-instance"
+cp /opt/openziti/etc/zrok/zrok-share.env ~/.zrok/zrok-share@${ZROK_INSTANCE}.env
+```
+
+## Edit the User Share Configuration File
+
+Edit the configuration file in `~/.zrok/zrok-share@${ZROK_INSTANCE}.env` as you would for [zrok frontdoor](/guides/frontdoor.mdx), except ignore the first section "ZROK ENVIRONMENT" because user shares re-use `~/.zrok` and do not need a separate zrok environment.
+
+## Start the User Share Service
+
+```bash
+systemctl --user enable --now zrok-share@${ZROK_INSTANCE}.service
+```
+
+## Check the User Share Journal
+
+```bash
+journalctl --user -lfu zrok-share@${ZROK_INSTANCE}.service
+```
+
+## Add Another User Share
+
+To create another user share, choose another instance name, copy the `zrok-share.env` file, edit the configuration file, and start the service.
