+- To remove the theme, run the program with the `--remove` option:
+    ```shell
+    python install.py -ra
+    ```
+- To reinstall the theme, run the program with the `--reinstall` option:
+    ```shell
+    python install.py -ri -a  # (other installation options)
+    ```
+  
+> [!TIP]
+> If you want to remove the GDM theme, use the `--gdm` option with the `--remove` option.
+
+
+The program allows you to specify the color of the theme and the mode to remove.
+For example, to remove purple and green themes in light mode, use the command:
+```shell
+python install.py -r --purple --green --mode light
+```
+
+Also, you can use the command above to reinstall purple and green themes in light mode with the `--reinstall` option.
+```shell
+python install.py -ri --purple --green --mode light
+```
+
+#### Options
+
+| Option           | Description           |
+|------------------|-----------------------|
+| -r, --remove     | Remove the theme      |
+| -ri, --reinstall | Reinstall the theme   |
