+CODE STYLE:
+  The coding style used by this project is enforced with clang-format using the
+  configuration contained in the .clang-format file in the root of the
+  repository.
+
+  Before pushing changes for review you can format your code with:
+  # Apply clang-format to modified .c, .h and .cc files
+  $ clang-format -i --style=file \
+    $(git diff --name-only --diff-filter=ACMR '*.[hc]' '*.cc')
+
+  Check the .clang-format file for the version used to generate it if there is
+  any difference between your local formatting and the review system.
+
+  See also: http://clang.llvm.org/docs/ClangFormat.html
