No problem, GH means GitHub 
It looks like the issue you’re having is related to a bug we found yesterday, which you can follow here: Documentation upload fails if tab not selected first · Issue #1390 · TykTechnologies/tyk · GitHub
When uploading the docs you need to click on one of the tabs at the top (like “From Swagger File”) before you paste it into the box, otherwise you run into this bug.
Hope that helps
