I want to add to this comment
Please consider using this wonderful tool. I dont suggest it because i hate this project, quite the opposite. I just want it to get better. Heck, i`d even do all the work with the text for free, if you do not have time or motivation, (PM me, in that case) but only with the one that is already written. New content will be up to you.
Free version doesnt allow spell check, but there are other tools for it.
Best of luck with the project <3
