+# Shell goodies
+
+A collection of shell enhancement for everyday happiness.
+
+## Setup
+
+```bash
+git clone git@github.com:mcataford/env.git ~/.env_goodies | . ./setup
+```
+
+## Updating existing setups
+
+Since `~/.env_goodies` is a cloned repository, pulling new changes should update everything. You may need to `source`
+the shell configuration file again for new goodies to apply.
