+# Compile Reason To Native With Dune
+
+[Dune](https://github.com/ocaml/dune) is "a composable build system for
+OCaml" with out-of-the-box support for ReasonML. Dune can be used for a lot
+of things, but in simplest terms it can be used to compile ReasonML programs
+into native executables.
+
+Considering the following ReasonML program.
+
+```reason
+/* hello_reason.re */
+print_endline("Hello, Reason!")
+```
+
+We can then create the following Dune build file.
+
+```lisp
+/* dune */
+(executable
+ (name hello_reason))
+```
+
+If we then run `dune build hello_reason.exe`, then Dune will compile the
+`hello_reason.re` into a `hello_reason.exe` executable that can be found in
+`build/default`. Run it and see the output.
+

+guide](https://dune.readthedocs.io/en/latest/quick-start.html).
