+Managing editor features
+========================
+
+Introduction
+------------
+
+In certain situations, it may be desirable to limit what features can be used
+in the Godot editor. For example, a UI designer on a team who doesn't need to
+see 3D features, or an educator slowly introducing features to students. Godot
+has a built in system called "feature profiles" to do this.
+
+With feature profiles, major features and nodes can be hidden from the editor.
+This only hides parts of the interface and does not actually remove support for
+these features, so scenes and scripts relying on those features will still work fine.
+This also means feature profiles are not an optimization technique. For
+information on how to optimize Godot see :ref:`doc_optimization`.
+
+Creating a profile
+------------------
+
+To manage editor features go to **Editor > Manage Editor Features**. This
+will open the **Manage Editor Feature Profiles** window. By default there
+will be no profile. Click on **Create Profile** and give it a name. You will
+then see a list of all the features in the Godot editor.
+

+
+The first section allows major editor features to be removed, such as the 3D
+editor or scripting editor. Below the main features is every class and node in
+Godot, which can be disabled as well. Click on a node and all of its properties
+and options will be listed in the **Extra Items** box, these can all be
+individually disabled.

+
+Sharing a profile
+-----------------
+
+To share profiles between editors click on the **Export** button. Save the custom
+profile somewhere as a ``.profile`` file. To use this in another editor open that
+editor's **Manage Editor Feature Profiles** window and click import, then select the
+``.profile`` file.
+
+This process is potentially cumbersome however if a large amount of computers need
+custom profiles. As an alternative, you can enable self-contained mode for Godot,
+which allows putting all editor configuration in the same folder as the editor binary.
+See :ref:`doc_data_paths_self_contained_mode` for details.
