+# iganaq Rust
+
+This is the Rust implementation of the iganaq prototype. See the [root README](../README.md) for the general description.
+
+## Configuration parser
+
+The configuration format follows a simple ini-style syntax and will silently ignore any unsupported keys. It does not validate values in any way.
