-### Debug the server
-
-The server is pushed to the device by the client on startup.
-
-To debug it, enable the server debugger during configuration:
-
-```bash
-meson x -Dserver_debugger=true
-# or, if x is already configured
-meson configure x -Dserver_debugger=true
-```
-
-Then recompile.
-
-When you start scrcpy, it will start a debugger on port 5005 on the device.
-Redirect that port to the computer:
-
-```bash
-adb forward tcp:5005 tcp:5005
-```
-
-In Android Studio, _Run_ > _Debug_ > _Edit configurations..._ On the left, click on
-`+`, _Remote_, and fill the form:
-
- - Host: `localhost`
- - Port: `5005`
-
-Then click on _Debug_.
