 * Remove as much content and HTML markup as possible, particularly content not associated with any entry (e.g. introduction, changelog, etc.).
 * Names must be as short as possible and unique across the documentation.
 * The number of types (categories) should ideally be less than 100.
-* Don't modify the icon sprite. I'll do it after your pull request is merged.
 
 ## Updating existing documentations
 
 Please don't submit a pull request updating the version number of a documentation, unless a change is required in the scraper and you've verified that it works.
 
-To ask that an existing documentation be updated, please use the [Trello board](https://trello.com/c/2B0hmW7M/52-request-updates-here).
+To ask that an existing documentation be updated, first check the last two [documentation versions reports](https://github.com/freeCodeCamp/devdocs/issues?utf8=%E2%9C%93&q=Documentation+versions+report+is%3Aissue+author%3Adevdocs-bot+sort%3Acreated-desc). Only create an issue if the documentation has been wrongly marked as up-to-date.
