        ## GROK IT

        Eclipse Ceylon is a **language for writing large programs in 
        teams.** To learn more, read the 15 minute 
        [quick intro](/documentation/current/introduction/),
        before taking the [tour](/documentation/current/tour/)
        of the language.

        ## TRY IT OUT

        The best way to try it out is to download the IDE and 
        **write some code**. Then you can explore the modules in 
        [Ceylon Herd](https://herd.ceylon-lang.org/). 
        Or you can try it [online](http://try.ceylon-lang.org/).

        This is a **community** project. Everything we produce is 
        [open source](/code/licenses/) and all our work happens 
        **out in the open** on [GitHub](https://github.com/eclipse)
        and [GitHub](https://github.com/ceylon).

          ## POWERFUL
  
          Eclipse Ceylon's powerful **flow-sensitive static type system** 
          catches many bugs while letting you express more, more 
          easily: **union and intersection types**, tuples, 
          function types, mixin inheritance, enumerated types, 
          and **reified generics**.

          ## READABLE
  
          We spend more time reading other people's code than 
          writing our own. Therefore, Eclipse Ceylon prioritizes 
          readability, via a **highly regular syntax**, support 
          for **treelike structures**, and elegant syntax sugar 
          where appropriate.

          ## PREDICTABLE
  
          Eclipse Ceylon **controls complexity with clarity**. The 
          language eschews <!--cryptic syntax and--> magical 
          implicit features with ambiguous corner cases. The 
          compiler follows **simple, intuitive rules** and 
          produces **meaningful errors**.

          ## A PLATFORM
  
          Eclipse Ceylon is a whole platform with a **modern SDK** designed 
          from scratch. It runs on both **Java** and **JavaScript** 
          virtual machines, bridging the gap between client and 
          server. Ceylon is **fully interoperable** with Java and 
          the Java SDK, and with JavaScript and its libraries.

          ## WITH MODULARITY
  
          Modularity is at the very core of the language, SDK, and 
          tooling. The compiler produces **module archives** which 
          are then distributed via a next-generation **repository 
          architecture** with **Ceylon Herd** as its social focus 
          point.

          ## AND TOOLING
  
          Static typing is the technology that enables **killer 
          tools**. Eclipse Ceylon comes with a complete **command line 
          toolset**, and an awesome **Eclipse based IDE** with 
          searching, refactoring, quick fixes + assists, 
          autocompletion, debugging, and much more.
