-# Tests
+# Apdu Dispatch
 
-For the tests to run locally for ApduDispatch, you need to enable std for logs.
+This layer accepts APDU (application packet data units) from a contact and/or contactless interface and passes them to a selected app.
 
-```
-cargo test --features std,log-all --target $(rustc -Vv | awk 'NR==5{print $2}')
-```
+It handles parsing APDU's, chaining, T=0, and T=1.
+
+Run tests via `cargo test --features std,log-all`
