* Add factory method * Fix return doc * Can not use "this" for return type of createCommand * Use return type of createCommand for subcommand * Add mention of .command from .createCommand * Remove trailing space * Add examples for createCommand * Explain example and make a little more realistic * Add comments pointing from .addCommand to .command One of the downsides of extra ways of adding and creating commands is confusion with the more common way. * Add createCommand to README * Shift command/subcommand contrast * Use single quotes in ts like in js, and clean up whitespace in new code
