 Breakpad is a set of client and server components which implement a
 crash-reporting system.
+
+
+-----
+Getting started in 32-bit mode (from trunk)
+Configure: CXXFLAGS=-m32 CFLAGS=-m32 CPPFLAGS=-m32 ./configure
+    Build: make
+     Test: make check
+  Install: make install
+
+If you need to reconfigure your build be sure to run "make distclean" first.
+
+
+-----
+To request change review:
+0. Get access to a read-write copy of source.
+   Owners at http://code.google.com/p/google-breakpad/ are able to grant
+   this access.
+
+1. Check out a read-write copy of source using instructions at
+   http://code.google.com/p/google-breakpad/source/checkout
+
+2. Make changes. Build and test your changes.
+   For core code like processor use methods above.
+   For linux/mac/windows, there are test targets in each project file.
+
+3. Download http://codereview.appspot.com/static/upload.py
+
+4. Run upload.py from the 'src' directory:
+   upload.py --server=breakpad.appspot.com
+
+   You will be prompted for credential and a description.
+
+5. At http://breakpad.appspot.com you'll find your issue listed; click on it,
+   and select Publish+Mail, and enter in the code reviewer and CC
+   google-breakpad-dev@googlegroups.com
+
+6. When applying code review feedback, specify the '-i' option when running
+   upload.py again and pass the issue number so it updates the existing issue,
+   rather than creating a new one.
+   Be sure to rerun upload.py from the same directory as you did for previous
+   uploads to allow for proper diff calculations.
