+===============================
+Enabling Slogging in DevStack
+===============================
+
+1. Download Devstack::
+
+    git clone https://git.openstack.org/openstack-dev/devstack
+    cd devstack
+
+2. Add this repo as an external repository in ``local.conf`` file::
+
+    [[local|localrc]]
+    enable_plugin slogging https://git.openstack.org/openstack/slogging
+
+   To use stable branches, make sure devstack is on that branch, and specify
+   the branch name to enable_plugin, for example::
+
+    [[local|localrc]]
+    enable_plugin slogging https://git.openstack.org/openstack/slogging <refspec>
+
+   In case triggered by cron, set environ variable ``SLOGGING_CRON``::
+
+    [[local|localrc]]
+    SLOGGING_CRON=True
+
+3. Run ``stack.sh``::
+
+    ./stack.sh
