+Introduction
+=============
+
+Yardstick is a project dealing with performance testing. Yardstick produces its own test cases but can also be considered as a framework to support feature project testing.
+
+Yardstick developed a test API that can be used by any OPNFV project. Therefore there are many ways to contribute to Yardstick.
+
+You can:
+
+* Develop new test cases
+* Review codes
+* Develop Yardstick API / framework
+* Develop Yardstick grafana dashboards and  Yardstick reporting page
+* Write Yardstick documentation
+
+This developer guide describes how to interact with the Yardstick project.
+The first section details the main working areas of the project. The Second
+part is a list of “How to” to help you to join the Yardstick family whatever
+your field of interest is.
+
+Where can I find some help to start?

+.. _`wiki page`: https://wiki.opnfv.org/display/yardstick/
+
+This guide is made for you. You can have a look at the `user guide`_.
+There are also references on documentation, video tutorials, tips in the
+project `wiki page`_. You can also directly contact us by mail with [Yardstick] prefix in the title at opnfv-tech-discuss@lists.opnfv.org or on the IRC chan #opnfv-yardstick.
+
+
+Yardstick developer areas
+==========================
+
+Yardstick framework
+--------------------
+
+Yardstick can be considered as a framework. Yardstick is release as a docker
+file, including tools, scripts and a CLI to prepare the environement and run
+tests. It simplifies the integration of external test suites in CI pipeline
+and provide commodity tools to collect and display results.
+
+Since Danube, test categories also known as tiers have been created to group
+similar tests, provide consistant sub-lists and at the end optimize test
+duration for CI (see How To section).
+
+The definition of the tiers has been agreed by the testing working group.
+
+The tiers are:
+
+* smoke
+* features
+* components
+* performance
+* vnf
+
+
+How Todos?
+===========
+
+How Yardstick works?
+---------------------
+
+The installation and configuration of the Yardstick is described in the `user guide`_.
+
+How can I contribute to Yardstick?
+-----------------------------------
+
+If you are already a contributor of any OPNFV project, you can contribute to
+Yardstick. If you are totally new to OPNFV, you must first create your Linux
+Foundation account, then contact us in order to declare you in the repository
+database.
+
+We distinguish 2 levels of contributors:
+
+* the standard contributor can push patch and vote +1/0/-1 on any Yardstick patch
+* The commitor can vote -2/-1/0/+1/+2 and merge
+
+Yardstick commitors are promoted by the Yardstick contributors.
+
+Gerrit & JIRA introduction
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. _Gerrit: https://www.gerritcodereview.com/
+.. _`OPNFV Gerrit`: http://gerrit.opnfv.org/
+.. _link: https://identity.linuxfoundation.org/
+.. _JIRA: https://jira.opnfv.org/secure/Dashboard.jspa
+
+OPNFV uses Gerrit_ for web based code review and repository management for the
+Git Version Control System. You can access `OPNFV Gerrit`_. Please note that
+you need to have Linux Foundation ID in order to use OPNFV Gerrit. You can get one from this link_.
+
+OPNFV uses JIRA_ for issue management. An important principle of change
+management is to have two-way trace-ability between issue management
+(i.e. JIRA_) and the code repository (via Gerrit_). In this way, individual
+commits can be traced to JIRA issues and we also know which commits were used
+to resolve a JIRA issue.
+
+If you want to contribute to Yardstick, you can pick a issue from Yardstick's
+JIRA dashboard or you can create you own issue and submit it to JIRA.
+
+Install Git and Git-reviews
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Installing and configuring Git and Git-Review is necessary in order to submit
+code to Gerrit. The `Getting to the code <https://wiki.opnfv.org/display/DEV/Developer+Getting+Started>`_ page will provide you with some help for that.
+
+
+Verify your patch locally before submitting
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Once you finish a patch, you can submit it to Gerrit for code review. A
+developer sends a new patch to Gerrit will trigger patch verify job on Jenkins
+CI. The yardstick patch verify job includes python flake8 check, unit test and
+code coverage test. Before you submit your patch, it is recommended to run the
+patch verification in your local environment first.
+
+Open a terminal window and set the project's directory to the working
+directory using the ``cd`` command. Assume that ``YARDSTICK_REPO_DIR`` is the path to the Yardstick project folder on your computer::
+
+  cd $YARDSTICK_REPO_DIR
+
+Verify your patch::
+
+  ./run_tests.sh
+
+It is used in CI but also by the CLI.
+
+Submit the code with Git
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Tell Git which files you would like to take into account for the next commit.
+This is called 'staging' the files, by placing them into the staging area,
+using the ``git add`` command (or the synonym ``git stage`` command)::
+
+  git add $YARDSTICK_REPO_DIR/samples/sample.yaml
+
+Alternatively, you can choose to stage all files that have been modified (that
+is the files you have worked on) since the last time you generated a commit,
+by using the `-a` argument::
+
+  git add -a
+
+Git won't let you push (upload) any code to Gerrit if you haven't pulled the
+latest changes first. So the next step is to pull (download) the latest
+changes made to the project by other collaborators using the ``pull`` command::
+
+  git pull
+
+Now that you have the latest version of the project and you have staged the
+files you wish to push, it is time to actually commit your work to your local
+Git repository::
+
+  git commit --signoff -m "Title of change"
+
+  Test of change that describes in high level what was done. There is a lot of
+  documentation in code so you do not need to repeat it here.
+
+  JIRA: YARDSTICK-XXX
+
+.. _`this document`: http://chris.beams.io/posts/git-commit/
+
+The message that is required for the commit should follow a specific set of
+rules. This practice allows to standardize the description messages attached
+to the commits, and eventually navigate among the latter more easily.
+
+`This document`_ happened to be very clear and useful to get started with that.
+
+Push the code to Gerrit for review
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Now that the code has been comitted into your local Git repository the
+following step is to push it online to Gerrit for it to be reviewed. The
+command we will use is ``git review``::
+
+  git review
+
+This will automatically push your local commit into Gerrit. You can add
+Yardstick committers and contributors to review your codes.
+

+   :width: 800px
+   :alt: Gerrit for code review
+
+You can find Yardstick people info `here <https://wiki.opnfv.org/display/yardstick/People>`_.
+
+Modify the code under review in Gerrit
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+At the same time the code is being reviewed in Gerrit, you may need to edit it
+to make some changes and then send it back for review. The following steps go
+through the procedure.
+
+Once you have modified/edited your code files under your IDE, you will have to
+stage them. The 'status' command is very helpful at this point as it provides
+an overview of Git's current state::
+
+  git status
+
+The output of the command provides us with the files that have been modified
+after the latest commit.
+
+You can now stage the files that have been modified as part of the Gerrit code
+review edition/modification/improvement using ``git add`` command. It is now
+time to commit the newly modified files, but the objective here is not to
+create a new commit, we simply want to inject the new changes into the
+previous commit. You can achieve that with the '--amend' option on the
+``git commit`` command::
+
+  git commit --amend
+
+If the commit was successful, the ``git status`` command should not return the
+updated files as about to be commited.
+
+The final step consists in pushing the newly modified commit to Gerrit::
+
+  git review
+
