 OPNFV CI
 ========
 
-TBD
+OPNFV continuous integration (CI) is ran on a variety of :doc:`hardware <resources>`
+connected to Jenkins and mangaged through YAML files in the `Releng`_
+repository. These YAML files are read by `Jenkins Job Builder`_ to
+generate and upload Jenkins jobs to the server. See the :doc:`User Guide
+<user-guide>` for resources on getting started with CI for your project.

 CI User Guide
 =============
 
-TBD
+Structure of the Releng Repository
+----------------------------------
+
+jjb/<projects>
+   Individual project CI configurations.
+
+jjb/global
+   Collection of JJB defaults and templates shared by all projects.
+
+global-jjb/
+   Git submodule pointing to `Global-JJB`_, which provides a variety of
+   common `CI jobs`_ such as ReadTheDocs
+   (RTD) builds.
+
+docs/
+  This documentation.
+
+releases/
+  Release configuration files for creating stable branches and tagging
+  repositories and related automation scripts.
+
+utils/
+  Collection of common utilities used by projects
+
+utils/build-server-ansible
+  Ansible configuration for managing build servers. This is where
+  projects can add packages they need for their CI to the servers.
+
+
+CI Setup
+--------
+
+Basic Setup
+~~~~~~~~~~~
+
+All projects are required to have a **+1 Verified** vote in Gerrit in
+order to merge their code. As a new project that comes in may not yet
+know how they want to setup CI, they can pass this validation by
+configuring a 'no-op' job to run against their changesets.
+
+1. Clone the `Releng`_ repository, using the *Clone with commit-msg
+   hook* command under the *SSH* tab (displayed after logging in and
+   uploading an SSH key):
+
+   .. note::
+     <gerrit username> in the command below will be your username in
+     Gerrit when viewing the command on the website.
+
+   For example::
+
+     git clone "ssh://<gerrit username>@gerrit.opnfv.org:29418/releng" && \
+     scp -p -P 29418 <gerrit username>@gerrit.opnfv.org:hooks/commit-msg "releng/.git/hooks/"
+
+
+2. Create a project directory under the *jjb/* directory, and an intial
+   project YAML file::
+
+     mkdir jjb/myproject
+     touch jjb/myproject/myproject-ci-jobs.yaml
+
+3. Modify the project YAML file to add the basic validation job::
+
+     $EDITOR jjb/myproject/myproject-ci-jobs.yaml
+
+   ::
+
+     ---
+     - project:
+         name: myproject
+         project:
+           - '{name}'
+         jobs:
+           - '{project}-verify-basic'
+
+Docker Builds
+~~~~~~~~~~~~~
+
+Docker build are managed through the **jjb/releng/opnfv-docker.yaml**
+file. Modify this file with your project details to enable docker builds
+on merges and tags to your project repository::
+
+  ---
+  - project:
+      name: opnfv-docker'
+
+      [...]
+
+      dockerrepo:
+        [...]
+        - 'myproject':
+          project: 'myproject'
+          <<: *master
+
+
+Documentation Builds
+~~~~~~~~~~~~~~~~~~~~
+
+Documentation is build using they Python Sphinx project. You can read
+more about how these build work and how your documentation should be
+setup in the `opnfvdocs`_ project.
+
+Create a file at **jjb/myproject/myproject-rtd-builds.yaml** with the
+following content::
+
+  ---
+  - project:
+      name: myproject-rtd
+      project: myproject
+      project-name: myproject
+
+      project-pattern: 'myproject'
+      rtd-build-url: <request from LFN IT>
+      rtd-token: <request from LFN IT>
+
+      jobs:
+        - '{project-name}-rtd-jobs'
+
+.. note::
+   Open a ticket with a link to the change adding your documentation
+   at `support.linuxfoundation.org`_ and the LFN IT team will
+   provide you the *rtd-build-url* and *rtd-token*.
+
+This will create jobs to build your project documentation (under *docs/*
+in your project repository) on proposed changes, and trigger a rebuild
+on the RTD site when code is merged in your project.
