# OCaml OCaml r2pipe bindings are maintained at [fxfactorial/ocaml-radare2](https://github.com/fxfactorial/ocaml-radare2). They are also published in opam repository as [`radare2`](https://opam.ocaml.org/packages/radare2). Note, the lowest supported version of radare2 is **2.3.0** - it's the first that started to support JSON r2pipe API consistently. Still, using newer versions is preferred. You can install it with [`opam`](https://opam.ocaml.org): ```sh opam install radare2 ```
