 # nix-update
 
-Currently interesting files `ups.sh, up.sh, check-result.sh`.
+[![Build Status](https://travis-ci.org/ryantm/nix-update.svg?branch=master)](https://travis-ci.org/ryantm/nix-update)
 
-1. get a list of oudated packages
+Scripts to try to update nixpkgs packages. Uses `hub` to automatically make PRs.
+
+# Instructions
+
+1. Clone this repo:
+```
+    git clone https://github.com/ryantm/nix-update
+```
+2. Get a list of oudated packages and place them in a `packages-to-update.txt` file in the root directory of this repository.
 
 ```
     git clone https://github.com/ryantm/repology-api.git
     cabal2nix --shell --hpack . > shell.nix && nix-build shell.nix && result/bin/repology-api > packages-to-update.txt
 ```
-2. Prepare a nixpkgs git repository where you want to do the updates. It expects `origin` to be where you want to push your updates. It clobbers any changes in that directory with `git reset --hard`. USE THIS ON A NEWLY CLONED REPO ONLY FOR THIS PURPOSE.
+3. `./ups.sh`
-3. copy list of ones you want to update into `ups.sh` ARGUMENTS variable
-4. delete update arguments that seem wrong. (Weird version strings, versions that don't seem like an update, the update version doesn't look like it would work with nixpkgs)
-5. Be in the directory of your update git repository. run `ups.sh` if it succeeds, it will make commits and push updates to the `origin` remote!
