-Repository to hold the various test inputs 
+# GlueCOSE Validation Suite
+
+**Caution: this is a work in progress in its very early stage.**
+
+This is a repository of GlueCOSE test cases.  Eventually, this will morph in to
+the GlueCOSE validation suite.
+
+Here's a first stab at the [CDDL schema](gluecose-schema.cddl) for specifying
+test cases as well as their results.
+
+And here's the first test case for a [successful Sign1](sign1-0000.json) that
+has been [validated](misc/gocose-result-sign1-0000.json) using the go-cose
+implementation.
+
+Implementation note: use `/dev/zero` as PRNG in order to make the randomised
+test deterministic.
