 Regex constraints are optional. Run this example with the `regex` feature enabled:
 
 ```sh
-cargo run -q -p decodal --features regex -- examples/regex/main.dcdl
+cargo run -q -p decodal-cli --features regex -- examples/regex/main.dcdl
 ```
 
 Without the feature, regex validation returns an unsupported feature diagnostic.
