After using the dashboard to locate problems, use the Teach editor to make your changes. 

All edits must be reviewed by the Content team before going live, so you will need to create and work in another branch. (Please allow 3-5 business days for edits to be reviewed and implemented. )

When you're finished, open a pull request on GitHub to the master branch and tag @datacamp-contentquality as the reviewer. A member of the team will let you know if they have any questions or concerns about your updates and then will either ask you for clarification or revision, then merge the changes live once approved.
