I recently wrote an article for okadaplugs.com, about my experience using their app (Okada Books) to self-publish my poetry collection.
I believe that the tips I listed would apply to anyone who wants to go down the self-publishing route, irrespective of what platform you decide to use.
I also talked about dealing with self-doubt as a writer, and the best ways you can use to tell people about your EBook.
You can read the article here: The Five Ps For Publishing On Okada Books.
