How to find MarkDown for a Page

Warning Newby question follows :slight_smile:

I am looking for the Markdown for Partner earned credit for managed services - Partner Center | Microsoft Docs But:
(1) The guidance at Set up Git repository locally - Contributor Guide | Microsoft Docs says there should be an " Edit link (pencil icon) on the upper right of the article." … But there is not ???
(2) When I go to github dot com MicrosoftDocs page and search for partner-center I seem to find the correct partner-center repo in all languages except english. Where is the English version ???

Sorry if the answer is obvious.
