+// statistics about the usage of your flag, you should append a marker comment
+// to the end of the feature name, like so:
 //   "my-special-feature",  // FLAGS:RECORD_UMA
 //
 // After doing that, run
 //   tools/metrics/actions/extract_actions.py
 // to add the metric to actions.xml (which will enable UMA to record your
 // feature flag), then update the <owner>s and <description> sections. Make sure
 // to include the actions.xml file when you upload your code for review!
 //
 // After your feature has shipped under a flag, you can locate the metrics under
 // the action name AboutFlags_internal-action-name. Actions are recorded once
 // per startup, so you should divide this number by AboutFlags_StartupTick to
 // get a sense of usage. Note that this will not be the same as number of users
 // with a given feature enabled because users can quit and relaunch the
 // application multiple times over a given time interval. The dashboard also
 // shows you how many (metrics reporting) users have enabled the flag over the
 // last seven days. However, note that this is not the same as the number of
 // users who have the flag enabled, since enabling the flag happens once,
 // whereas running with the flag enabled happens until the user flips the flag
 // again.
