Decker can be used for authoring many forms of interactive media, including choice- or parser-based IF, visual novels, and zines. There’s official reference documentation for the project, but it’s a bit dry, and the included tutorials tend to narrowly focus on specific features or libraries.
My good friend Ahmwma just published an interactive book built in and all about Decker, full of examples and delightful pixel art. While it doesn’t focus specifically on IF, I think it’s a wonderful overview of the sorts of projects that are possible in Decker, and I hope it sparks inspiration for a few of you!
