## Trial
You cn get an appropriate nix-shell with the binaries installed by first testing this with:
```
nix-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:
```
> nix repl
nix-repl> pkgs = import <nixpkgs> {}
nix-repl> drvs = import (pkgs.fetchFromGitHub {
owner = "justinwoo";
repo = "easy-dhall-nix";
rev = # some REV
sha256 = # some SHA
}) {}
nix-repl> drvs.dhall-simple
«derivation /nix/store/qz29jbplpmlvsbmq05084dh1fbs8sl0h-dhall-simple.drv»

## NixOS: Contributors needed
The derivations here have been tested by others to work on NixOS. If you have problems, open an issue.
