Underscores.Me is a free service from the developers of WordPress and Automattic but still its not much popular like other WordPress services. Underscores provides you a starter WordPress theme which is not intended to be a parent theme. You can hack it with your own codes and there will be no waiting for its updates to come in future.

Its easy to download; simply visit Underscores.Me then give your theme a name, click generate button to download you theme. After downloading your theme you can upload it to your WordPress site, activate then start your editing and make it yours.
