OCaml Docs

The OCaml documentation system (odoc) doesn't support documenting multiple versions. The [ocaml-docs] workflow can be used to generate documentation for all ocaml- tags (releases).

Creating a new release

When creating a new release an ocaml- tag with the new version number is created. (1) After creating the tag the gh-pages job must be triggered to create the new, tagged ocaml documentation. (2) After creating the docs, a link to them must be added to the table in hacl-ocaml/readme.md.
