 When you contribute a new query to Semmle/ql for inclusion in the standard queries, you should also write a query help file. This file provides detailed information about the purpose and use of the query, which is available to users in LGTM (for example [here](https://lgtm.com/rules/1506093386171/)) and on the query homepages:
