I have experience the frustration of setting up ocaml, opam, dune locally hence I created this template repo for anyone who wants to get started quicker on writing ocaml code.

OCaml boilerplate(https://github.com/chen2073/ocaml_boilerplate)

You will need some basic understanding of docker and dune so please glance through the docs.

This boilerplate repo aims to help you run ocaml dev environment or execute ocaml code in docker to reduce the hassle of running thing locally. And some boilerplate dune project files to make dune available for the setup.
