 $ pipx install pssecret-server[hiredis]
 ```
 
+After that just run the app with
+
+```console
+$ pssecret-server
+```
+
+This will start the [uvicorn](https://www.uvicorn.org/) server on `127.0.0.1:8000`.
+Available configuration options:
+
+```
+--host TEXT        Bind socket to this host.  [default: 127.0.0.1]
+--port INTEGER     Bind socket to this port. If 0, an available port will be
+                   picked.  [default: 8000]
+--uds TEXT         Bind to a UNIX domain socket.
+--workers INTEGER  Number of worker processes.  Defaults to the
+                   $WEB_CONCURRENCY environment variable if available, or 1.
+--help             Show this message and exit.
+```
+
+#### If you'd like more control
+
+Create virtual environment, install application, run using [uvicorn](https://www.uvicorn.org/) directly.
+
+```console
+$ python -m venv .venv
+$ source .venv/bin/activate
+$ pip install pssecret-server
+$ uvicorn pssecret_server.main:app --workers 4 --uds /path/to/socket.sock
+```

+You can also run [uvicorn](https://www.uvicorn.org/) without activating virtualenv, e.g. from SystemD service
+
+```console
+$ /path/to/your/.venv/bin/python -m uvicorn pssecret_server.main:app --workers 4 --uds /path/to/socket.sock
+```
