Besides managning your DNS settings manually as described How to configure DNS, we have also introduced support for DNSimple's "one click services". This service allows you to easily sync your domain settings with your Divio projects in a matter of a few clicks.
First step is to login at DNSimple.com and select your domain in the overview, then navigate to "Services" and click on "Add or edit services".
Now in the one-click services overview, scroll down until you find the service called Divio Aldryn and select Add service.
Here you have to enter the Aldryn Project Domain. If you're not sure what this is, go to the Divio Control Panel, select your project and check its Domain settings.
Once you've entered the project domain, hit Complete Divio Aldryn Setup to confirm.
