You can get a full documentation of command line options by running stark without options or stark -h.
The general structure is: stark COMMAND [OPTIONS].
Commands:
| build | Compile output into build/ |
| docs | Start a web server with the documentation. |
| new PATH | Create an example site at PATH. |
| serve | Compile into build/ and start a web server. |
| watch | Compile and start automatic recompile process. |
| watch-server | Compile, start "watch" process and a web server. |
I recommend using stark watch-server for development and stark build for automated builds.
