+OPNFV XCI Developer Sandbox
+###########################
+
+The XCI Developer Sandbox is created by the OPNFV community for the OPNFV
+community in order to
+
+- provide means for OPNFV developers to work with OpenStack master branch,
+ cutting the time it takes to develop new features significantly and testing
+ them on OPNFV Infrastructure
+- enable OPNFV developers to identify bugs earlier, issue fixes faster, and
+ get feedback on a daily basis
+- establish mechanisms to run additional testing on OPNFV Infrastructure to
+ provide feedback to OpenStack community
+- make the solutions we put in place available to other LF Networking Projects
+ OPNFV works with closely
+
+More information about OPNFV XCI and the sandbox can be seen on
+`OPNFV Wiki <https://wiki.opnfv.org/pages/viewpage.action?pageId=8687635>`_.
+
+===================================
+Components of XCI Developer Sandbox
+===================================
+
+The sandbox uses OpenStack projects for VM node creation, provisioning
+and OpenStack installation.
+
+- **openstack/bifrost:** Bifrost (pronounced bye-frost) is a set of Ansible
+ playbooks that automates the task of deploying a base image onto a set
+ of known hardware using ironic. It provides modular utility for one-off
+ operating system deployment with as few operational requirements as
+ reasonably possible. Bifrost supports different operating systems such as
+ Ubuntu, CentOS, and openSUSE.
+ More information about this project can be seen on
+ `Bifrost documentation <https://docs.openstack.org/developer/bifrost/>`_.
+
+- **openstack/openstack-ansible:** OpenStack-Ansible is an official OpenStack
+ project which aims to deploy production environments from source in a way
+ that makes it scalable while also being simple to operate, upgrade, and grow.
+ More information about this project can be seen on
+ `OpenStack Ansible documentation <https://docs.openstack.org/developer/openstack-ansible/>`_.
+
+- **opnfv/releng:** OPNFV Releng Project provides additional scripts, Ansible
+ playbooks and configuration options in order for developers to have easy
+ way of using openstack/bifrost and openstack/openstack-ansible by just
+ setting couple of environment variables and executing a single script.
+ More infromation about this project can be seen on
+ `OPNFV Releng documentation <https://wiki.opnfv.org/display/releng>_`.
+
+==========
+Basic Flow
+==========
+
+Here are the steps that take place upon the execution of the sandbox script
+``xci-deploy.sh``:
+
+1. Sources environment variables in order to set things up properly.
+2. Installs ansible on the host where sandbox script is executed.
+3. Creates and provisions VM nodes based on the flavor chosen by the user.
+4. Configures the host where the sandbox script is executed.
+5. Configures the deployment host which the OpenStack installation will
+ be driven from.
+6. Configures the target hosts where OpenStack will be installed.
+7. Configures the target hosts as controller(s) and compute(s) nodes.
+8. Starts the OpenStack installation.
+
+=====================
+Sandbox Prerequisites
+=====================
+
+In order to use this sandbox, the host must have certain packages installed.
+
+- libvirt
+- python
+- pip
+- git
+- <fix the list with all the dependencies>
+- passwordless sudo
+
+The host must also have enough CPU/RAM/Disk in order to host number of VM
+nodes that will be created based on the chosen flavor. See the details from
+`this link <https://wiki.opnfv.org/display/INF/XCI+Developer+Sandbox#XCIDeveloperSandbox-Prerequisites>`_.
+
+===========================
+Flavors Provided by Sandbox
+===========================
+
+OPNFV XCI Sandbox provides different flavors such as all in one (aio) which
+puts much lower requirements on the host machine and full-blown HA.
+
+* aio: Single node which acts as the deployment host, controller and compute.
+* mini: One deployment host, 1 controller node and 1 compute node.
+* noha: One deployment host, 1 controller node and 2 compute nodes.
+* ha: One deployment host, 3 controller nodes and 2 compute nodes.
+
+See the details of the flavors from
+`this link <https://wiki.opnfv.org/display/INF/XCI+Developer+Sandbox#XCIDeveloperSandbox-AvailableFlavors>`_.
+
+==========
+How to Use
+==========
+
+Basic Usage
+-----------
+
+clone OPNFV Releng repository
+
+ git clone https://gerrit.opnfv.org/gerrit/releng.git
+
+change into directory where the sandbox script is located
+
+ cd releng/prototypes/xci
+
+execute sandbox script
+
+ sudo -E ./xci-deploy.sh
+
+Issuing above command will start aio sandbox deployment and the sandbox
+should be ready between 1,5 and 2 hours depending on the host machine.
+
+Advanced Usage
+--------------
+
+The flavor to deploy, the versions of upstream components to use can
+be configured by developers by setting certain environment variables.
+Below example deploys noha flavor using the latest of openstack-ansible
+master branch and stores logs in different location than what is configured.
+
+clone OPNFV Releng repository
+
+ git clone https://gerrit.opnfv.org/gerrit/releng.git
+
+change into directory where the sandbox script is located
+
+ cd releng/prototypes/xci
+
+set the sandbox flavor
+
+ export XCI_FLAVOR=noha
+
+set the version to use for openstack-ansible
+
+ export OPENSTACK_OSA_VERSION=master
+
+set where the logs should be stored
+
+ export LOG_PATH=/home/jenkins/xcilogs
+
+execute sandbox script
+
+ sudo -E ./xci-deploy.sh
+
+Warning::
+
+ Please encure you always execute the sandbox script using **sudo -E**
+ in order to make the environment variables you set available to the
+ sandbox script or you end up with the default settings.
+
+===============
+User Variables
+===============
+
+All user variables can be set from command line by exporting them before
+executing the script. The current user variables can be seen from
+``releng/prototypes/xci/config/user-vars``.
+
+The variables can also be set directly within the file before executing
+the sandbox script.
+
+===============
+Pinned Versions
+===============
+
+As explained above, the users can pick and choose which versions to use. If
+you want to be on the safe side, you can use the pinned versions the sandbox
+provides. They can be seen from ``releng/prototypes/xci/config/pinned-versions``.
+
+How Pinned Versions are Determined
+----------------------------------
+
+OPNFV runs periodic jobs against upstream projects openstack/bifrost and
+openstack/ansible using latest on master and stable/ocata branches,
+continuously chasing the HEAD of corresponding branches.
+
+Once a working version is identified, the versions of the upstream components
+are then bumped in releng repo.

+
+=======
+Testing
+=======
+
+Sandbox is continuously tested by OPNFV CI to ensure the changes do not impact
+users. In fact, OPNFV CI itself uses the sandbox scripts to run daily platform
+verification jobs.
+
+=======
+Support
+=======
+
+OPNFV XCI issues are tracked on OPNFV JIRA Releng project. If you encounter
+and issue or identify a bug, please submit an issue to JIRA using
+`this link <https://jira.opnfv.org/projects/RELENG>_`.
+
+If you have questions or comments, you can ask them on ``#opnfv-pharos`` IRC
+channel on Freenode.
