+### RuntimeAPI PoC
+
+1. Use chopsticks to start a local chain with the RuntimeAPI enabled: `make run`
+2. Build guest programs: `make guests`
+3. Run test runner to display hex-encoded `args` in tracing logs: `cargo run -p pvq-test-runner -- --program output/<guest-program>`
+4. Upload `program` and `args` in PJS UI.

 ### XCM Integration PoC
 
 The test case of XCM integration is located in `vendor/polkadot-sdk/polkadot/xcm/xcm-simulator/example/src/tests.rs`
