I am closing this because although i appreciate the effort that you put into going over all the grammatical and I guess capitalization mistakes (Github vs GitHub), this PR is a bit unnecessary. I am going to close it and I encourage you to focus more on the actual code and programming issues, rather than spelling ones.

I often start to work on projects by opening small PR to see how changes and feedbacks are welcome.

Based on the fact, you deny a PR that simply try to fix minor things, and you manage to disappoint me, I will pass trying to focus on bigger changes on this repository.
