 Getting the Source
 ------------------
 
-There are two primary ways of getting Google Test's source code: you
-can download a stable source release in your preferred archive format,
-or directly check out the source from our Subversion (SVN) repository.
-The SVN checkout requires a few extra steps and some extra software

+The GitHub repository offers stable tagged releases available as .ZIP archives. 
+A Git checkout requires a few extra steps and some extra software
 packages on your system, but lets you track the latest development and
 make patches much more easily, so we highly encourage it.
 
 ### Source Package ###
 
-Google Test is released in versioned source packages which can be
-downloaded from the download page [1].  Several different archive
-formats are provided, but the only difference is the tools used to
-manipulate them, and the size of the resulting file.  Download
-whichever you are most comfortable with.
-
-  [1] http://code.google.com/p/googletest/downloads/list

-Once the package is downloaded, expand it using whichever tools you
-prefer for that type.  This will result in a new directory with the
-name "gtest-X.Y.Z" which contains all of the source code.  Here are
-some examples on Linux:
