-## Getting your ReviewBoard Account
+The next step is to prepare your patch and then send us a Pull Request via the Github Web UI.

+## Submitting a Pull Request
 
-## Setting up your ReviewBoard Environment
+Follow the instructions outlined in the
+[Github Documentation](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request)
 
-Run `./rbt status`. The first time this runs it will bootstrap and you will be asked to login.
-Subsequent runs will cache your login credentials.
+If possible, make a link to the issue this PR is solving by adding the `#` followed by the number
+of the issue it is addressing.
 
-## Submitting a Patch for Review
-
-Post a review with `rbt`, fill out the fields in your browser and hit Publish.
-
-    ./rbt post -o

-If you're unsure about who to add as a reviewer, you can default to adding Stephan Erb (StephanErb) and
-Renan DelValle (rdelvalle). They will take care of finding an appropriate reviewer for the patch.
-
-Once you've done this, you probably want to mark the associated Jira issue as Reviewable.

-## Updating an Existing Review

-Incorporate review feedback, make some more commits, update your existing review, fill out the
-fields in your browser and hit Publish.

 ### Merging Your Own Review (Committers)
 
-Once you have shipits from the right committers, merge your changes in a single commit and mark

-Note that even if you're developing using feature branches you will not use `git merge` - each
