+
+===========
+OCC Command
+===========
+
+This API allows you to register the occ (CLI) commands.
+The principal is similar to the regular Nextcloud OCC command for PHP apps, that are working in context of the Nextcloud instance,
+but for ExApps it is a trigger via Nextcloud OCC interface to perform some action on the External App side.
+
+
+.. note::
+
+    Passing files directly as an input argument to the occ command is not supported.
