Hi @Lygaen,
Can you explain a bit more what you are trying to accomplish? That documentation file is only for the std library for Zig. If you are trying to build your own docs, you may want to look at other codebases that generate docs.
For example, DVUI docs are generated with a build step that uses a custom index.html. I believe this is copied from the zig lib docs and modified for the look and feel of DVUI. You could do something similar. The build.zig file for DVUI has a build step for generating the docs files
Yeah, you will have to go the DVUI route for that. If you want a custom logo or anything like that, you will need to copy it out and generate it yourself.
That being said, I thing this will be something people run into more in the future. It would be convenient if getEmittedDocs took an optional parameter that allowed for custom templates.
