+Modify configurations from a Git repository
+===========================================
+
+If you have an internal or external Git repository set up for
+your environment, you can store and modify Fuel and OpenStack
+configurations in this repository and apply changes to your
+environments. This approach enables you to modify the settings
+you typically cannot modify through the Fuel web UI.
+
+The functionality is implemented through an additional Infrastructure-as-
+a-Code extension to Fuel. You need to clone the
+``fuel-nailgun-extension-iac`` repository
+on your Fuel Master node before you can use this feature.
+
+With the Infrastructure-as-a-Code extension to Fuel you can:
+
+* Associate a Git repository with a specific OpenStack environment.
+* Perform management operations, such as create, read, update, and delete
+  (CRUD), with the files in the repository.
+* Audit changes and enforce operations in the OpenStack environment.
+* List the applied changes.
+* Manage white lists for the applied changes.
