+  # On adding coverage annotations to the code in the GitHub
+  # Code Review for now:
+  #
+  # - The annotations consume a lot of space in the PR code review,
+  #   and can make it hard to review files that are not covered yet.
+  #
+  # - The coverage can be visited using the Codecov link at all times.
+  #   https://app.codecov.io/gh/xapi-project/xen-api/pulls
+  #
+  # - The annotations can be hidden in GitHub PR code review by
+  #   pressing the "a" key or by deselecting the "Show comments"
+  #   checkbox but they are shown by default.
+  #
+  # - The Codecov Chrome and Firefox extension is a much nicer
+  #   way to indicate coverage:
+  #
+  #   Link: https://github.com/codecov/codecov-browser-extension
+  #
+  #   - How to enable: You need to log in to Codecov using Github.
+  #     For Firefox, enable the needed permissions:
