Best way to include a github project docs inside a Hugo site

[Tzach_Livyatan]

Hello all, newbie question below.
We are building a Hugo base site for an open source project
As part (not all) of the site, I want to include HTML rendering of the project /doc directory (Markdown files).
What is the right way to do so?

I started by creating a git submodule for the opensource project under the Hugo, but I’m not sure what I should do next. What should I change in config.toml to include the submodule in the build?
Should/can I use a different theme for the submodule

Thanks
Tzach

Hugo as a documentation tool

As the documentation of Hugo is rendered by Hugo itself, I wonder if there’s any plan to add some documentation features to Hugo. Actually the main feature I miss is valid for any website: an internal search. I couldn’t find any open issue for this. Maybe it’s outside the scope of Hugo? Would you recommend an external tool? A feature more specific for documentation would be a classic ‘book index’. What do you think about it?

You mean you want to include a pre-rendered set of files? Or, do you mean you want Hugo to render the markdown files into HTML.

If you already have HTML, you can put them under static and link to it from the site however you need.

If you want to have Hugo render them, then, this is untested but I would say you could pull a git submodule into content like content/docs. Their frontmatter would need to be compatible.
