Everyone does it differently...
I add the accounts, verify them and start the tools with default settings, just so the accounts are little bit active.
Next day, I change name, username and add bio. Tools are still running on default (Follow, Like, couple of comments per day).
Day after that, I add link, leave the tools running on default for one more day and then set them up to work as I described above.
Since the accounts start to do a lot of actions on Instagram, it becomes suspicious and they usually ask for phone verification 12-24 hours later. Do the phone verification and let them work again.
