+- System with OpenRC installed and configured.
+- Administrative privileges (doas or sudo).
+- `ytlocal` script located at `/usr/sbin/ytlocal` and application files in an accessible directory.

+## Service Installation
+
+1. **Create the OpenRC service script** `/etc/init.d/ytlocal`:
+
+   ```sh
    #!/sbin/openrc-run
    # Distributed under the terms of the GNU General Public License v3 or later
    name="yt-local"

+   > [!TIP]
+   > To store the PID in a different location, adjust the `pidfile` variable in the service script.

+   > Verify that the virtual environment (`venv`) is correctly set up and that `python` points to the appropriate version.
 
-3. OpenRC check
+   > [!CAUTION]
+   > Do not stop the process manually; use OpenRC commands (`rc-service ytlocal stop`) to avoid race conditions.
 
-- status: `doas rc-service ytlocal status`
+   > [!NOTE]
-- start: `doas rc-service ytlocal start`
+   > When run with administrative privileges, the configuration is saved in `/root/.yt-local`, which is root‑only.

-- disable: `doas rc-update del ytlocal`
 
-When yt-local is run with administrator privileges,
+- **Status**: `doas rc-service ytlocal status`
-the configuration file is stored in /root/.yt-local
+- **Start**: `doas rc-service ytlocal start`
+- **Restart**: `doas rc-service ytlocal restart`
+- **Stop**: `doas rc-service ytlocal stop`
+- **Enable at boot**: `doas rc-update add ytlocal default`
+- **Disable**: `doas rc-update del ytlocal`
+
+## Post‑Installation Verification
+
+- Confirm the process is running: `doas rc-service ytlocal status`
+- Inspect logs for issues: `doas tail -f /var/log/ytlocal.log` (if logging is configured).
+
+## Troubleshooting Common Issues
+
+- **Service fails to start**: verify script permissions, correct `command=` path, and that the virtualenv exists.
+- **Port conflict**: adjust the server’s port configuration before launching.
+- **Import errors**: ensure all dependencies are installed in the virtual environment.
+
+[!IMPORTANT]
+Keep the service script updated when modifying startup logic or adding new dependencies.
