Basics¶ ↑

Decko (formerly known as “Wagn”) makes serious web development fun.

Decko creators, or “Sharks”, have used Decko to create open community sites, private knowledge management sites, public proposal submission sites with private back-ends for review, project management systems, wikis, blogs, journals, forums, and more.

Install Decko, open a webpage, and get started. With Decko’s wiki-inspired building blocks, you can collaborate from day one on content, design, and structure create elegant web systems on the fly. And ruby developers can take these creations even further with Decko’s development framework. Decko’s innovative Mods API supports boundless creativity while integrating seamlessly with structures created on the site.
