- Select the icon to open the Plugins Browser. This is where you can find and install plugins.
- You can also install from URL in the Settings menu. We do not recommend installing plugins from untrusted sources.
- To install a plugin, select the "Install" button on the plugin you want. You can also select a version from a dropdown menu, but this is not recommended.
- To update, uninstall, and reload plugins, navigate to the Decky menu and select the icon.
- Keep in mind that uninstalling a plugin will only remove its plugin files, not any other files it may have created.
