 - **key**: the identifier for the menu and URL path. For instance, if it is `general_assemblies` we will have a new menu entry for the url `<host>/general_assemblies` and the name specified in the I18n key `decidim.participatory_processes.scoped_participatory_process_slug_prefixes.general_assemblies`.
 - **position_in_menu**: Where to place the item in the main menu, the usual "PROCESSES" item have the value `2.0`, lower this number will put it before and vice-versa.
 - **slug_prefixes**: and array of prefixes for the slug of the participatory process. All participatory processes that have an slug starting with this word will be listed here and not in the normal "PROCESSES" menu.
+
+#### Extra menu items for participatory processes & assemblies
+
+Extra menu items in a participatory process (or an assembly) can defined in addition to the ones generated by the components.
+
+Works exclusively using ENV vars following this scheme:
+
+1. Add an ENV var like `EXTRA_PROCESS_MENU_***` where `***` is the slug of a participatory process.
+2. Set the value of that ENV var to a pair of a model and a slug of a participatory space, separated by a slash `/`, for instance: `Decidim::Assembly/some-assembly` or `Decidim::ParticipatoryProcess/some_process`
+3. A new menu item will appear to link the referenced participatory space
+4. Also works for assemblies, examples:
+  `EXTRA_ASSEMBLY_MENU_MY_ASSEMBLY=Decidim::ParticipatoryProcess/my_process`
+  `EXTRA_PROCESS_MENU_MY_PROCESS=Decidim::Assembly/my_assembly`
+  `EXTRA_PROCESS_MENU_MY_PROCESS=Decidim::ParticipatoryProcess/my_process`
