+FFI
+===
+
+*** Warning: Turns out this is a really bad idea, do not use! When the BEAM calls native functions it needs to know how many reductions should be used. Otherwise calling a long running function can break the scheduling completly, because with this approach a long running function is considered 1 reduction ***
+
+An easy way to call external functions (e.g. C functions) from [Elixir](https://github.com/elixir-lang/elixir).
+
+Inspired by [Ruby's FFI](https://github.com/ffi/ffi)
+
+** This is alpha software **
+
+## Example Program
+
+```elixir
+defmodule MyLib do
+  use FFI.Library, name: "libstdc++.so.6"
+
+  attach_function :puts, [:string], :int
+end
+
+MyLib.puts("Hello World from C stdlib")
+```
+
+## Installation
+
+The package can be installed by adding `ffi` to your list of dependencies in `mix.exs`:
+
+```elixir
+def deps do
+  [{:ffi, git: "https://github.com/joshnuss/elixir-ffi.git"}]
+end
+```
+
+## Running Examples
+
+```shell
+mix run examples/basic.exs
+```
