+# NIF for Elixir.Tree
+
+## To build the NIF module:
+
+- Your NIF will now build along with your project.
+
+## To load the NIF:
+
+```elixir
+defmodule Tree do
+ use Rustler, otp_app: :genetic, crate: "tree"
+
+ # When your NIF is loaded, it will override this function.
+ def add(_a, _b), do: :erlang.nif_error(:nif_not_loaded)
+end
+```
+
+## Examples
+
+[This](https://github.com/rusterlium/NifIo) is a complete example of a NIF written in Rust.
