Now go to your domain DNS settings, add a text record to with the host or name of _atproto.{handle}

So mine would be _atproto.kieran.dongerz.one

To get your domain to respond as a handle you need to give it your 'did'

First go to your bluesky settings, Account, Handle. Select I have my own domain and copy the part in the Value field.

Fill out your desired handle here (my domain is dongerz.one, but my handle is kieran.dongerz.one)
