+Today, we are excited to release Dotty version 0.3.0-RC2. This release
 serves as a technology preview that demonstrates new language features
 and the compiler supporting them.
 
+If you’re not familiar with Dotty, it's a platform to try out new language concepts and compiler
+technologies for Scala. The focus is mainly on simplification. We remove extraneous syntax
+(e.g. no XML literals), and try to boil down Scala’s types into a smaller set of more fundamental
+constructors. The theory behind these constructors is researched in
+[DOT](https://infoscience.epfl.ch/record/215280), a calculus for dependent object types.
+You can learn more about Dotty on our [website](http://dotty.epfl.ch).
