Nice! Do you think it could be adapted to other docs sites?
I made a small clone of the tutorials section (https://clone-swiftui-tutorial.vercel.app/) where the content is already Markdown (and use codehike to turn the markdown into a rich UI). This made me realize that codehike is AI-friendly, in the sense that even for non-linear UIs the original content is still AI-readable Markdown.
To be fair, it may be the "biggest change ever", but it doesn't change too much. It buff some units that were bad, nerf some units and techs that were too good. But the general meta remains the same. The devs are really good at introducing changes.
I maintain one of the selected projects. $20k means that I can focus on the project without taking any freelance work on the side for a while. Hopefully making the project more attractive to sponsors, hopefully snowballing into more OSS and less freelance.
As the maintainer of one of the selected projects (https://codehike.org/), I really appreciate what GitHub is doing, putting the money and trying different approaches (last year it was $450K across 900 projects).
My approach with Code Hike (https://codehike.org/) was to add a sponsor-wall to some parts of the docs, not sure if it falls under any of those categories. It's working decently well ($600 per month).
If you want to try it, beware that current docs are minimal. If you have questions or feedback GitHub Discussions is the best place to post them. Thanks!
