Nitpick — how about:

You can use the help command to remind you of all available options and usage. It also works with...

That makes the sentence focus on the user and not the command.

@stffndk By this, do you mean the same Information block? Would like to keep things DRY if possible.

Perhaps something like the following:

The help command is available to remind you of all available options and usage patterns. It also works in conjunction with the build, serve, and new subcommands, e.g, jekyll help new or jekyll help build.

@admhlt done.

@chrisfinazzo yeah, I was a bit relunctant too, but I inserted a slightly modified version less visible at the end of the quickstart page to give it a shot though. It can not hurt.
