+# github.com/gobuffalo/packd
+
+This is a collection of interfaces designed to make using [github.com/gobuffalo/packr](https://github.com/gobuffalo/packr) easier, and to make the transition between v1 and v2 as seamless as possible.
+
+They can, and should, be used for testing, alternate Box implementations, etc...

+## Installation
+
+```bash
+$ go get -u -v github.com/gobuffalo/packd

+github.com/gobuffalo/packd does not try to reinvent the wheel! Instead, it uses the already great wheels developed by the Go community and puts them all together in the best way possible. Without these giants, this project would not be possible. Please make sure to check them out and thank them for all of their hard work.
