Pull Request to Dockrails

Hello,
Need to correct some missing verb.
However, on the master branch of dockrails they have mentioned - “Rails branch for quick doc fixes, please DO NOT OPEN PULL REQUESTS IN HERE”
May i know which branch should i pull for update?

Pull requests can be raised in https://github.com/rails/rails

I need pull request https://github.com/rails/docrails.

Not to rails.

Any documentation changes intended for Rails guides or api which require review should be done on https://github.com/rails/rails. rails/docrails is a branch/copy of the rails/rails repository and people with commit access directly push to docrails if they are confident of the changes. Or they send in a pull request on rails/rails.
