+====================
+Enabling in Devstack
+====================
+
+1. Download DevStack::
+
+    git clone https://github.com/openstack-dev/devstack.git
+    cd devstack
+
+2. Add this repo as an external repository::
+
+     > cat local.conf
+     [[local|localrc]]
+     enable_plugin glare https://github.com/openstack/glare
+
+   .. note::
+       To enable installation of glare client from git repo instead of pypi execute
+       a shell command:
+
+       .. code-block:: bash
+
+         export LIBS_FROM_GIT+=python-glareclient
+
+3. run ``stack.sh``
