Asciidoc and Antora. We document a product that has a bunch of micro services and each micro service is in a separate git repository. We store our documentation alongside the related code in git, so it is spread out across several git repositories. Antora makes it simple to pull asciidoc files from multiple git repositories and compile it all into one static site. It also has good search functionality and support for versioning using either git branches or tags.
