Hi and thanks for making this cheat sheet - good idea!
It looks like that pull request was only sent to your personal repository (), not to the DuckDuckGo repository. Please could you try to send a pull request with your new cheat sheet to the repository. The way to do this is, after commiting your code, to your personal repository and then, through the GitHub website, send a pull request to the DuckDuckGo repository.
There's a video tutorial here: https://vimeo.com/148366187
or the documentation here: http://docs.duckduckhack.com/submitting/...
I'd also recommend asking for help in the #ask-anything Slack channel. If you need an invite just send an empty email to firstname.lastname@example.org
