+# Code Coverage
+
+## Categories of coverage
+
+*   executed - this line of code was hit during execution
+*   instrumented - this line of code was part of the compilation unit, but not
+    executed
+*   missing - in a source file, but not compiled.
+*   ignored - not an executable line, or a line we don't care about
+
+Coverage is calculated as `exe / (inst + miss)`. In general, lines that are in
+`miss` should be ignored, but our exclusion rules are not good enough.
+
+## Buildbots
+
+Buildbots are currently on the
+[experimental waterfall](http://build.chromium.org/buildbot/waterfall.fyi/waterfall).
+The coverage figures they calculate come from running some subset of the
+chromium testing suite.
+
+*   [Linux](http://build.chromium.org/buildbot/waterfall.fyi/builders/Linux%20Coverage%20(dbg))
+    - uses `gcov`
+*   [Windows](http://build.chromium.org/buildbot/waterfall.fyi/builders/Win%20Coverage%20%28dbg%29)
+*   [Mac](http://build.chromium.org/buildbot/waterfall.fyi/builders/Mac%20Coverage%20%28dbg%29)
+
+Also,
+
+*   [Coverage dashboard](http://build.chromium.org/buildbot/coverage/)
+*   [Example coverage summary](http://build.chromium.org/buildbot/coverage/linux-debug/49936/)
+    - the coverage is calculated at directory and file level, and the directory
+    structure is navigable via the **Subdirectories** table.
+
+## Calculating coverage locally
+
+TODO
+
+## Advanced Tips
+
+Sometimes a line of code should never be reached (e.g., `NOTREACHED()`). These
+can be marked in the source with `// COV_NF_LINE`. Note that this syntax is
+exact.
