+This directory contains example programs that use [Wuffs the
+Library](/doc/wuffs-the-library.md). See [Hello `wuffs-c`](/hello-wuffs-c) for
+an example program that uses [Wuffs the Language](/doc/wuffs-the-language.md)
+and its `wuffs-c` compiler.

Finally, there are admittedly a couple of TODOs in this directory, concerning
some rough edges in what should be a simple example. Version 0.2 (December
