How does one jump to definition?

[mimoo]

I followed the installation instructions but it is not clear from the README how one should use this plugin. How do I jump to definition, for example?

I've found some stackoverflow answer saying that C-c C-l should work, but I'm getting this error:

No annotation file. Compile with option "-annot" or set ‘caml-annot-dir’.

@mimoo It's best to install Merlin alongside Tuareg (or lsp-mode/elgot which use Merlin internally for OCaml) and leverage it for the definition lookup. See https://ocaml.github.io/merlin/ for details.
