Thanks for the review @tykee. I really appreciate it.
I must say I'm a bit surprised and disappointed by the low evaluation.

In terms of formatting and grammar I have checked it, with the Hemingway app, and read it carefully my self. Probably there is something that I have missed, but the lowest score on this feels a bit harsh to me.
Also in terms of adding value to the open source community. No value at all, is harsh as well.
