The account wizard will appear on your first log in to Prospect Rocket. If you exit the software before you complete the wizard, the unfinished area will show on your next login so you can complete them.
Once you have completed the setup/welcome wizard you will be unable to access that wizard again. However, if you need to update anything from the wizard (Personal Info, Email Setup, Twilio Setup, Etc.) you can find all the same information able to be edited in your Account and Settings areas.
