June 24, I have no idea what I'm doing, feel free to message me if you know how to make a paperback extension haha.

My try at paperback sources, this time with a little more experience

Want to develop your own source?

You can reverse engineer the extensions common repo, currently here on GitHub.

According to NmN's 0.8 extension and some others, you can check out the extensions common repo here (archive.org], use one of the current implementations in the repo as an example, and/or ask in Paperback's official Discord server, but the discord link is expired and the page isn't helpful at all :/
