I wasn’t paid to write these guides. Ben asked me to do it as a favor to him. Considering all that he’s done for our community I felt it was the least I could do. To be honest even though it took about 2 months to build and document, I had a lot of fun doing it. It forced me to write guides in a manner that was easy for everyone to understand and cleanup my Github so I could share any files that were used that aren’t part of the original download. You’re not obligated but if you would like, feel free to donate.
