 Documentation
 =============
 
-TBD
+Using docs.openstack.org
+------------------------
+
+Translated documents are available at the OpenStack Documentation site.
+It is updated daily. Most contents are linked from either of:
+
+* http://docs.openstack.org/<lang> contains released documents.
+  Follow "More Releases and Languages" in http://docs.openstack.org/.
+* http://docs.openstack.org/draft/draft-index.html contains
+  draft (unreleased) documents.
+
+TBD: How to enable translated document generation for your language
+and add links to the above index pages.
+At the moment, ask it in the i18n mailing list.
 
 OpenStack Dashboard
 ===================
 
-TBD
+Translation check site
+----------------------
+
+The infra and i18n teams are preparing the translation check site
+to check dashboard translations. It is under preparation.
+
+Running DevStack
+----------------
+
+Another convenient way is to check dashboard translations is to run
+DevStack in your local environment.  To run DevStack, you need to
+prepare ``local.conf`` file, but no worries. Several ``local.conf``
+files are shared, for example [#]_. From my experience, you need a
+machine with two or four CPU core, 8 GB memory and 20 GB disk to run
+DevStack comfortablely.
+
+.. code-block:: console
+
+   $ git clone http://git.openstack.org/openstack-dev/devstack.git
+   $ cd devstack
+   <prepare local.conf>
+   $ ./stack.sh
+   <wait and wait... it takes 20 or 30 minutes>
+
+Translations are being imported into a project repository daily,
+so in most cases you do not need to pull translations from Zanata
+manually.
