Not to make you feel bad or something, but if you're going to create a guide/tutorial, probably create one on a topic that hasn't been written before. Or if you're going to create a tutorial on a topic that has like a bajillion articles already, at least attempt to beat those existing articles in terms of quality and information. This one seems to be just written in under 10 minutes.
I hope this helps someone
Sorry to say but it really won't.
