+# 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
+```
+
+## Memory Box
+
+The [`packd#MemoryBox`](https://godoc.org/github.com/gobuffalo/packd#MemoryBox) is a complete, thread-safe, implementation of [`packd#Box`](https://godoc.org/github.com/gobuffalo/packd#Box)
