For information on how to use MODX to create a web site (and other topics), see my main web site, Bob's Guides, or better yet, buy my book: MODX: The Official Guide.

Looking for high-quality, MODX-friendly hosting? As of May 2016, Bob's Guides is hosted at A2 hosting. MODX will work fine at most hosting services, but having a MODX-friendly host can prevent a lot of frustration. Better yet, the A2 Solid-State-Drive servers are configured to handle the many Ajax and database calls made by MODX — especially the MODX Manager. My Manager runs about four times as fast as it did on my previous host. I particularly recommend the Swift package with the Performance Plus option.
