+# buildpack-deps
+
+In spirit, `buildpack-deps` is similar to Heroku's stack images. It includes a large number of "development header" packages needed by various things like Ruby Gems, PyPI modules, etc. For example, `buildpack-deps` would let you do a `bundle install` in an arbitrary application directory without knowing beforehand that ssl.h is required to build a dependent module.
+
+## Usage Notes
+
+Primary used as a base image:
+
+```
+FROM docker.io/boxcutter/buildpack-deps:[version]
+```
