Update README file

README

+About
+=====
+
+This is meant to be a more Linux packaging friendly copy of the AudioProcessing
+module from the WebRTC[1] project. The ideal case is that we make no changes to
+the code to make tracking upstream code easy.
+
+This package currently only includes the AudioProcessing bits, but I am very
+open to collaborating with other projects that wish to distribute other bits of
+the code and hopefully eventually have a single point of packaging all the
+WebRTC code to help people reuse the code and avoid keeping private copies in
+several different projects.

+Notes
+=====
+
+Assembling some quick notes on maintaining this tree vs. the original WebRTC
+project source code.
+
+1. Running meld on a pristine tree's src/ vs. the same directory in the WebRTC
+   code should produce a fairly easy-to-parse set of differences that can be
+   merged. I've kept the test code out for now, but this might get merged in
+   the future. The .gyp/.gypi files are included to make tracking addition and
+   removal of files easy to track.
+
+2. Be sure to keep the keep the comment on top of the version field in
+   configure.ac up-to-date so that it's easy to track what changes went in at
+   what point.
