GitHub sha: be88ac8b

I think [a-f] should be enough since it’s the first character of the SHA.

Is that what the character represent? I went with [a-z] because I have no knowledge of what format the URL follows.

I guess a-z is safer but I’m pretty sure it’s the first character of the hash of the upload.
