DudaOne differs from DudaMobile in many ways. The main differences are that it is built for three screens instead of one, there is no syncing, and it completely replaces the desktop site. For these reasons when transitioning to a DudaOne site from a DudaMobile site, it's important not to think of it as an addition to your site but as an upgrade and replacement to it.
You can begin using DudaOne by either entering your current site's domain into the "start with URL" text box on www.dudaone.com or by pressing the "start with template" option.
Once you've done so, we'll import content from your existing site or bring you to the default DudaOne template. Either way, you can start editing! The DudaOne editor keeps almost all of its tools on the left side of your screen, so you have much more room to work with than you did with DudaMobile.
Remember to use the device icons at the top of the screen to check out what your site looks like on each device before publishing. Unlike in DudaMobile, changes you make in one format will immediately affect each other format.
In DudaMobile, you need to add a script to your desktop site to get it to redirect to the mobile site. In DudaOne, this isn't necessary - DudaOne IS your desktop site. All you need to do to activate your DudaOne site is either use your provided .dudaone.com URL or create a CNAME and activate your chosen custom URL.
