+
+If you are interested in understanding the internals of Google Test,
+building from source, or contributing ideas or modifications to the
+project, then this document is for you.
+
+# Introduction #
+
+First, let's give you some background of the project.
+
+## Licensing ##
+
+All Google Test source and pre-built packages are provided under the [New BSD License](http://www.opensource.org/licenses/bsd-license.php).
+
+## The Google Test Community ##
+
+The Google Test community exists primarily through the [discussion group](http://groups.google.com/group/googletestframework) and the GitHub repository.
+You are definitely encouraged to contribute to the
+discussion and you can also help us to keep the effectiveness of the
+group high by following and promoting the guidelines listed here.
+
+### Please Be Friendly ###
+
+Showing courtesy and respect to others is a vital part of the Google
+culture, and we strongly encourage everyone participating in Google
+Test development to join us in accepting nothing less. Of course,
+being courteous is not the same as failing to constructively disagree
+with each other, but it does mean that we should be respectful of each
+other when enumerating the 42 technical reasons that a particular
+proposal may not be the best choice. There's never a reason to be
+antagonistic or dismissive toward anyone who is sincerely trying to
+contribute to a discussion.
+
+Sure, C++ testing is serious business and all that, but it's also
+a lot of fun. Let's keep it that way. Let's strive to be one of the
+friendliest communities in all of open source.
+
+As always, discuss Google Test in the official GoogleTest discussion group.
+You don't have to actually submit code in order to sign up. Your participation
+itself is a valuable contribution.
+
+# Working with the Code #
+
+If you want to get your hands dirty with the code inside Google Test,
+this is the section for you.
+
+## Compiling from Source ##
+
+Once you check out the code, you can find instructions on how to
+compile it in the [README](../README.md) file.
+
+## Testing ##
+
+A testing framework is of no good if itself is not thoroughly tested.
+Tests should be written for any new code, and changes should be
+verified to not break existing tests before they are submitted for
+review. To perform the tests, follow the instructions in
+[README](../README.md) and verify that there are no failures.
+
+# Contributing Code #
+
+We are excited that Google Test is now open source, and hope to get
+great patches from the community. Before you fire up your favorite IDE
+and begin hammering away at that new feature, though, please take the
+time to read this section and understand the process. While it seems
+rigorous, we want to keep a high standard of quality in the code
+base.
+
+## Contributor License Agreements ##
+
+You must sign a Contributor License Agreement (CLA) before we can
+accept any code.  The CLA protects you and us.
+
+  * If you are an individual writing original source code and you're sure you own the intellectual property, then you'll need to sign an [individual CLA](http://code.google.com/legal/individual-cla-v1.0.html).
+  * If you work for a company that wants to allow you to contribute your work to Google Test, then you'll need to sign a [corporate CLA](http://code.google.com/legal/corporate-cla-v1.0.html).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it.
+
+## Coding Style ##
+
+To keep the source consistent, readable, diffable and easy to merge,
+we use a fairly rigid coding style, as defined by the [google-styleguide](http://code.google.com/p/google-styleguide/) project.  All patches will be expected
+to conform to the style outlined [here](http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml).
+
+## Updating Generated Code ##
+
+Some of Google Test's source files are generated by the Pump tool (a
+Python script).  If you need to update such files, please modify the
+source (`foo.h.pump`) and re-generate the C++ file using Pump.  You
+can read the PumpManual for details.
+
+## Submitting Patches ##
+
+Please do submit code. Here's what you need to do:
+
+  1. A submission should be a set of changes that addresses one issue in the [issue tracker](https://github.com/google/googletest/issues). Please don't mix more than one logical change per submittal, because it makes the history hard to follow. If you want to make a change that doesn't have a corresponding issue in the issue tracker, please create one.
+  1. Also, coordinate with team members that are listed on the issue in question. This ensures that work isn't being duplicated and communicating your plan early also generally leads to better patches.
+  1. Ensure that your code adheres to the [Google Test source code style](#Coding_Style.md).
+  1. Ensure that there are unit tests for your code.
+  1. Sign a Contributor License Agreement.
+  1. Create a Pull Request in the usual way.
+
+## Google Test Committers ##
+
+The current members of the Google Test engineering team are the only
+committers at present. In the great tradition of eating one's own
+dogfood, we will be requiring each new Google Test engineering team
+member to earn the right to become a committer by following the
+procedures in this document, writing consistently great code, and
+demonstrating repeatedly that he or she truly gets the zen of Google
+Test.
+
+# Release Process #
+
+We follow a typical release process:
+
+  1. A release branch named `release-X.Y` is created.
+  1. Bugs are fixed and features are added in trunk; those individual patches are merged into the release branch until it's stable.
+  1. An individual point release (the `Z` in `X.Y.Z`) is made by creating a tag from the branch.
+  1. Repeat steps 2 and 3 throughout one release cycle (as determined by features or time).
+  1. Go back to step 1 to create another release branch and so on.
