-### Building in general on host development machine
+### Building on host development machine
 Run `"make"` on macos or linux (or in fact RPi also) host to build these binaries:
 * `target/debug/piggui` - GUI version without GPIO, to enable UI development on a host
 * `target/aarch64-unknown-linux-gnu/release/piggui` - GUI version for Pi with GPIO, can be run natively from RPi command line
 * `target/aarch64-unknown-linux-gnu/release/piglet` - Headless version for Pi with GPIO, can be run natively from RPi command line
 
+Use `"make run"` to start `piggui` on the local machine - for GUI development.
