 ### Server side

 To develop on the server-side:
 
 ```bash
-    $ npm run dev:server
+$ npm run dev:server
 ```
 
 Then, the server will listen on `localhost:9000`. When server source files
 change, these are automatically recompiled and the server will automatically

 To develop on the client side:

 The API will listen on `localhost:9000` and the frontend on `localhost:3000`.
 Client files are automatically compiled on change, and the web browser will
 reload them automatically thanks to hot module replacement.
