GitHub has introduced a new addition to its exclusive T-Shirt Family, following the success of their previous "fork you" and "all your rebase are belong to us" shirts. The latest offering is an American Apparel Ash Grey tee featuring a seven-color screen print on the front and a small GitHub logo on the back. GitHub emphasizes the quality of the shirt and encourages potential buyers to act quickly as supplies are limited. The announcement was made by Tom Preston-Werner, also known by his handle @mojombo.
