In February the folks at ThemeShaper, the home of the Automattic Theme Team, released Underscores, or _s for short. Anyone can download the _s theme at github, but in order to fork it, you previously had to make a number of search and replace substitutions.
The good news is that this is no longer the case, thanks to the new Underscores.me website. It allows you to generate your own Underscores-based theme with your custom theme name and the search and replace already complete.
What’s so cool about Underscores?
