If you are getting started in OCaml, you'll have to understand how the tooling works to move along.
This basic examples explains the basic scaffolding we'll use from now on.
./lib/: contains our application's logic../bin/: start our app
cd ./00-hello-world
# Compile and run `main.ml`
dune exec ./bin/main.exe
You can also load your project into a REPL, with dune utop
# open My_lib;;
# Greetings.world;;
- : string = "Hello, World!"
