 ## Purpose
 
-This repository will serve as an interim pipeline for our finished Shibboleth IDP container image process.  We may refactor later, but managing the configuration tree inline makes sense right now.
+The docker/shib-idp directory contains many prerequisites to run a Shibboleth IDP service.  But no container distributed by TIER can contain all the relevant configuration required to run the Shibboleth IDP service.  Our design calls for this repository to integrate Shibboleth IDP with end-user managed configuration trees and produce a working service.
+
+## Prerequisites
+
+This repository does use docker/util, so you should install the binscripts.
+
+The specific command will be in the BINSCRIPTS.md file at this level.
+
+## Quickstart
+
+```
+bin/rebuild.sh
+bin/test.sh
+````
+
+These commands will clear the traces of any existing images you have, rebuild the container image, and run the test suite against them.
