+# Uninstall using the quick install script
+
+The Funkwhale quick install script doesn't currently offer an uninstall command. This is because you may be using its dependencies for other software. To uninstall a quick install Funkwhale installation, follow the instructions in this guide.
+
+```{warning}
+Removing Funkwhale data is __irreversible__. Make sure you [back up your data](../upgrade_docs/backup.md).

+
+## Stop the Funkwhale server
+
+Before you uninstall anything from your server, you need to stop the Funkwhale systemd services.
+
+1. Stop all systemd services listed under the `funkwhale` target
+
+   ```{code} bash
+   sudo systemctl stop funkwhale.target
+   ```
+
+2. Disable all systemd services to prevent launch at startup.
+
+   ```{code} bash
+   sudo systemctl disable funkwhale-server
+   sudo systemctl disable funkwhale-worker
+   sudo systemctl disable funkwhale-beat
+   ```
+
+3. Remove the service files.
+
+   ```{code} bash
+   sudo rm /etc/systemd/system/funkwhale-server.service
+   sudo rm /etc/systemd/system/funkwhale-worker.service
+   sudo rm /etc/systemd/system/funkwhale-beat.service
+   sudo rm /etc/systemd/system/funkwhale.target
+   ```
+
+4. Reload all services to pick up the changes.
+
+   ```{code} bash
+   sudo systemctl daemon-reload
+   sudo systemctl reset-failed
+   ```
+
+## Remove the reverse proxy
+
+To stop serving Funkwhale from your web server, you need to remove your reverse proxy configuration.
+
+````{tabbed} Nginx
+
+1. Remove the configuration files from your web host.
+
+   ```{code} bash
+   sudo rm /etc/nginx/sites-enabled/funkwhale.conf
+   sudo rm /etc/nginx/sites-available/funkwhale.conf
+   sudo rm /etc/nginx/funkwhale_proxy.conf
+   ```
+
+2. Reload the web server.
+
+   ```{code} bash
+   sudo systemctl reload nginx
+   ```
+
+````
+
+````{tabbed} Apache2
+
+1. Remove the configuration files from your web host.
+
+   ```{code} bash
+   sudo rm /etc/apache2/sites-enabled/funkwhale.conf
+   sudo rm /etc/apache2/sites-available/funkwhale.conf
+   ```
+
+2. Reload the web server.
+
+   ```{code} bash
+   sudo service apache2 restart
+   ```
+
+````
+
+## Remove the Funkwhale database
+
+```{warning}
+This action is __irreversible__. Make sure you have [backed up your data](../upgrade_docs/backup.md) before proceeding.
+```
+
+Once you have stopped the Funkwhale services, you can remove the Funkwhale database.
+
+1. Navigate to your Funkwhale directory.
+
+   ```{code} bash
+   cd /srv/funkwhale
+   ```
+
+2. Delete the Funkwhale database.
+
+   ```{code} bash
+   sudo -u postgres psql -c 'DROP DATABASE funkwhale;'
+   ```
+
+3. Delete the Funkwhale user.
+
+   ```{code} bash
+   sudo -u postgres psql -c 'DROP USER funkwhale;'
+   ```
+
+## Delete  the Funkwhale account
+
+```{warning}
+This action deletes the `/srv/funkwhale/` directory. Make sure you have [backed up any data](../upgrade_docs/backup.md) you want to keep.
+```
+
+Once you have removed the database, you can delete the `funkwhale` user and all associated data.
+
+```{code} bash
+sudo userdel -r funkwhale
+```
+
+This deletes the `funkwhale` user and everything in their home directory (`/srv/funkwhale/`). If your content is hosted in an S3-compatible store, you need to delete this data separately.
