Set it up

Where it usually goes wrong
- A username with consecutive hyphens or a hyphen at the ends — not allowed
- Leaving the bio empty; it appears in search and on every contribution
- Not setting a profile README for an organisation account
Skip the guesswork
SetMySocial writes your GitHub bio to exactly 160 characters, checks whether the username is free, and exports the picture at the right size.
