+### Manage Plugins
+
+To list all available plugins type:
+
+```bash
+./webodm.sh plugin list
+```
+
+To enable/disable a plugin type:
+
+```bash
+./webodm.sh plugin enable <plugin name>
+./webodm.sh plugin disable <plugin name>
+./webodm.sh restart
+```
+
+On some platforms (eg. Windows), if you want to manage plugins, you will need to make sure that the `./plugins` directory can be mounted as a docker volume and then pass the `--mount-plugins-volume` flag to `webodm.sh`. Check the docker documentation.

 ## Customizing and Extending
 
 Small customizations such as changing the application colors, name, logo, or addying custom CSS/HTML/Javascript can be performed directly from the Customize -- Brand/Theme panels within WebODM. No need to fork or change the code.
