-## Command line on Windows
-
-Some Windows users are not familiar with the command line. Here is how to open a
-terminal and run `scrcpy` with arguments:
-
- 1. Press <kbd>Windows</kbd>+<kbd>r</kbd>, this opens a dialog box.
- 2. Type `cmd` and press <kbd>Enter</kbd>, this opens a terminal.
- 3. Go to your _scrcpy_ directory, by typing (adapt the path):
-
-    ```bat
-    cd C:\Users\user\Downloads\scrcpy-win64-xxx
-    ```
-
-    and press <kbd>Enter</kbd>
- 4. Type your command. For example:
-
-    ```bat
-    scrcpy --record file.mkv
-    ```
-
-If you plan to always use the same arguments, create a file `myscrcpy.bat`
-(enable [show file extensions] to avoid confusion) in the `scrcpy` directory,
-containing your command. For example:
-
-```bat
-scrcpy --prefer-text --turn-screen-off --stay-awake
-```
-
-Then just double-click on that file.
-
-You could also edit (a copy of) `scrcpy-console.bat` or `scrcpy-noconsole.vbs`
-to add some arguments.
