+/**
+ * This class allows executing or registering new Joplin commands. Commands
+ * can be executed or associated with
+ * {@link JoplinViewsToolbarButtons | toolbar buttons} or
+ * {@link JoplinViewsMenuItems | menu items}.
+ *
+ * [View the demo plugin](https://github.com/laurent22/joplin/tree/dev/packages/app-cli/tests/support/plugins/register_command)
+ *
+ * ## Executing Joplin's internal commands
+ *
+ * It is also possible to execute internal Joplin's commands which, as of
+ * now, are not well documented. You can find the list directly on GitHub
+ * though at the following locations:
+ *
+ * * [Main screen commands](https://github.com/laurent22/joplin/tree/dev/packages/app-desktop/gui/MainScreen/commands)
+ * * [Global commands](https://github.com/laurent22/joplin/tree/dev/packages/app-desktop/commands)
+ * * [Editor commands](https://github.com/laurent22/joplin/tree/dev/packages/app-desktop/gui/NoteEditor/commands/editorCommandDeclarations.ts)
+ *
+ * To view what arguments are supported, you can open any of these files
+ * and look at the `execute()` command.
