Underscores is an online tool for creating a starter theme in WordPress.

It saves a lot of time because it inserts the name of the theme with an underscore in the variable names in a boilerplate theme. If you activate this theme, it’s just basic text and nothing else.

There’s still more to do to create a WP theme, but it certainly is better than rolling your own.

1. Select theme name (my theme is anddeakdb). Press Generate.

2. The generated starter theme zip file (andeakdb.zip) should have automatically downloaded.

3. Unzip the file folder (andeakdb) into the WordPress wp-content > themes folder.

Now, this theme should be an option in the WordPress Admin Panel under
Appearance > Themes.
