+
+davinci.js is a framework to build visual elments for the qlik sense plattform.
+
+The most important design principal is that you can use the visual element easy
+as qlik extension in the qlik sense enterprise, but also to use it in own
+angular websites with just Enigma.JS and without the whole qlik.js stack.
+
+The rest design principals:
+* accessibility, screenreader ready and keybord usage / shortcuts
+* ready for versioning, possibility to run different versions of the plugin or elements
+  in one page
+* stay close to the qlik ux
+
+The plan is in the end to get even angular 1.x and angular 4+ elements out
+of one codebase.
+
