+deze commando's kun je uitvoeren op de command-line als je alle build tools
+goed geïnstalleerd hebt. er hoort ook een configuratie te zijn voor visual
+studio code.
+
+```sh
+make                    # build
+make flash              # upload executable to robot
+make clean              # clean working directory
+make format             # format source and header files
+make compile_commands   # generate compile_commands.json (clangd)
+```
