1. godaddy: cancel privacy/ domain lock
2. godaddy request authorization code. get email. (update:  new UI gives you it on godaddy.com directly, don’t need email)
3. namesilo: request transfer of domain.
4. namesilo: enter authorization code in email from step 2 (and pay). get email
5. follow link in email from step 4 to accept transfer (takes like 5 minutes to godaddy’s, i.e. current, email address) (update: 1-2 hour-ish, though this step became obsolete and I could just skip to step 6)
6. godaddy -> domain (dropdown) -> transfer -> accept (takes another few minutes for it to appear in dropdown)
