+## OCaml/Reason - opam
+
+This example requires you to have `opam.locked` file which you can generate with `opam lock .`.
+
+It's worth noting that even if lock file was change, it might be optimal to restore previous cache, so `hashFiles` in the key and if statement in "Save opam cache" step are optional.
+```yaml

+      with:
+        path: _opam
+        key: ${{ runner.os }}-opam-${{ hashFiles('opam.locked') }}
