Improve Documentation UI for Better Readability and Navigation

[SinghAstra]

Hi there 👋,

I was exploring the documentation of khoj and noticed that the current UI could be more user-friendly in terms of readability and navigation.

Is there any particular reason behind the current design of the docs UI?

I’d love to help improve it! If you're open to suggestions, I recommend a cleaner and more modern layout—something similar to DocumentX. This is my repo and it is open source. I would love to add custom components too. I am more than happy to help with the migration. I believe this could enhance the user experience significantly.

I'd be happy to contribute and help redesign the docs UI. Let me know your thoughts!

Thanks 😊
