+# Easy Dhall Nix
+
+[![Build Status](https://travis-ci.org/justinwoo/easy-dhall-nix.svg?branch=master)](https://travis-ci.org/justinwoo/easy-dhall-nix)
+
+Derivations for easily downloading Nix binaries and putting them to use.
+
+## Trial
+
+You cn get an appropriate nix-shell with the binaries installed by first testing this with:
+
+```
+nix-shell -A shell
+```
+
+## Installation
+
+You might choose to simply copy the derivations from this repository, or you can fetch the git/Github repo using the various helpers.
+
+## NixOS: Contributors needed
+
+If you want to use this in NixOS, then please supply some PRs for the appropriate patchelf voodoo.
