This is an improved OCaml language / standard-library docset for Dash.
Compared to Dash's official docset for OCaml, this one is more up-to-date and has better accuracy and usability too.
You must have python3 and make installed.
Clone this repository and then run make in its directory. The OCaml reference manual will automatically be downloaded, and then transformed into ./generated/ocaml-unofficial.docset
In the Dash application, choose Preferences > Docsets > [+] > Add Local Docset and select the generated docset mentioned above.
