Themelets are an extension for Morph and you easily install the themelet of your choice using Morph's Configurator.
Themelets provide the character of your website, the colors and images that make it unique and set it apart from the crowd.
With Morph you always have the same optimized "engine" (Morph core framework) but can have multiple themelets.
Every themelet has its own specific settings needed for it to work with the engine, so each themelet has a guide to help you set it up as quickly as possible.
If you are familiar with xhtml and css you can build your own themelets to use with Morph. We will provide solid documentation for developers in the near future.
