Update README for usage

[Mobilpadde]

I'm a tad confused on how to use this tool? An explanation in the README would be much appreciated!

Thanks

You are right - that's definitely something we should add...

Also, I guess it'd be a good idea to be a bit more verbose in the --help output:

Usage:
  pb [command]

Available Commands:
  clone
  edit
  generate
  help        Help about any command
  lint
  new
  path
  run
  test

Flags:
  -h, --help   help for pb

Use "pb [command] --help" for more information about a command.

I agree. Also, the help-flag for a command is almost non-existent :smile:
