Nothing is better than learning stuff yourself. Though I think there are people out there who don't have time to learn it or just don't want to spend time finding out themselves.

Though if you're planning on selling it, you definitly have to add screenshots or something to prove that your ebook is way more detailed than other peoples ebook.

i thougt of that but the problem about that is, if i add Screenshots then You would see the book and what´s the point of it when im selling it?

Not necessarily. If you have a detailed ebook, I'm guessing you also have pictures in the ebook. For example upload a picture where you're correcting a bad config and show another screenshot where you show something small. People need proof that it's an original, made by you ebook. That's all.

I just did that and yeah don´t know but it´s a little proof
