- Compile a sketch:

`arduino-builder -compile {{path/to/sketch.ino}}`

- Specify the debug level (default: 5):

`arduino-builder -debug-level {{1..10}}`

- Specify a custom build directory:

`arduino-builder -build-path {{path/to/build_directory}}`

- Use a build option file, instead of specifying `--hardware`, `--tools`, etc. manually every time:

`arduino-builder -build-options-file {{path/to/build.options.json}}`

- Enable verbose mode:

`arduino-builder -verbose {{true}}`
