+# Origin Story
+
+## Google Mondrian
+
+Google developed [Mondrian], a Perforce based code review tool to
+facilitate peer-review of changes prior to submission to the central
+code repository.  Mondrian is not open source, as it is tied to the
+use of [Perforce] and to many Google-only services, such as
+[Bigtable].  Google employees have often described how useful Mondrian
+and its peer-review process is to their day-to-day work.
+
+[Mondrian]: http://video.google.com/videoplay?docid=-8502904076440714866
+[Perforce]: http://www.perforce.com/
+[Bigtable]: http://research.google.com/archive/bigtable.html
+[Rietveld]: http://code.google.com/p/rietveld/
+
+## Rietveld
+
+Guido van Rossum open sourced portions of Mondrian within [Rietveld],
+a similar code review tool running on Google App Engine, but for use
+with Subversion rather than Perforce.  Rietveld is in common use by
+many open source projects, facilitating their peer reviews much as
+Mondrian does for Google employees.  Unlike Mondrian and the Google
+Perforce triggers, Rietveld is strictly advisory and does not enforce
+peer-review prior to submission.
+
+## Gitosis and Gitolite
+
+Git is a distributed version control system, wherein each repository
+is assumed to be owned/maintained by a single user.  There are no
+inherent security controls built into Git, so the ability to read from
+or write to a repository is controlled entirely by the host's
+filesystem access controls.  When multiple maintainers collaborate on
+a single shared repository a high degree of trust is required, as any
+collaborator with write access can alter the repository.
+
+[Gitosis] and [Gitolite] provide tools to secure centralized Git
+repositories, permitting multiple maintainers to manage the same
+project at once, by restricting the access to only over a secure
+network protocol, much like Perforce secures a repository by only
+permitting access over its network port.

+
+## Android
+
+The [Android Open Source Project][AOSP] (AOSP) was founded by Google
+by the open source releasing of the Android operating system.  AOSP
+has selected Git as its primary version control tool.  As many of the
+engineers have a background of working with Mondrian at Google, there
+is a strong desire to have the same (or better) feature set available
+for Git and AOSP.
+
+[AOSP]: http://source.android.com/
+
+## The Rietveld fork
+
+Gerrit Code Review started as a simple set of patches to Rietveld, and
+was originally built to service AOSP.  This quickly turned into a fork
+as we added access control features that Guido van Rossum did not want
+to see complicating the Rietveld code base.  As the functionality and
+code were starting to become drastically different, a different name
+was needed.  Gerrit calls back to the original namesake of Rietveld,
+[Gerrit Rietveld](http://en.wikipedia.org/wiki/Gerrit_Rietveld), a
+Dutch architect.
+
+## Gerrit 2.x rewrite
+
+Gerrit 2.x is a complete rewrite of the Gerrit fork, changing the
+implementation from Python on Google App Engine, to Java on a J2EE
+servlet container and a SQL database.
