        <h1 id="why-dotty">Why Dotty?</h1>
        <p>
            Dotty is 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
            <a href="https://infoscience.epfl.ch/record/215280">DOT</a>, a
            calculus for dependent object types.
        </p>

        <div class="centered-text">
            <p>Yes, it will be - eventually.</p>

        <div class="centered-text">
            <p>
                <a href="#getting-started">You can!</a> But it currently comes with
                no guarantees of stability.

        <h1 id="is-there-scala-2-interop">Is there Scala 2 interop?</h1>
        <div class="centered-text">
            <p>
                Dotty currently interops with libraries compiled with Scala
                2.11 - but not 2.12

        <h1 id="how-do-i-migrate-my-code-to-dotty">How do I migrate my code to Dotty?</h1>
        <p>
            An automated rewriting tool is planned for Dotty, more on this to come.
            Scala 2 sources can be compiled to some degree by issuing:
        </p>
        <pre class="sourceCode bright"><code>./bin/dotc -language:Scala2 file.scala</code></pre>
        <p>when compiling your program.</p>

            Using Dotty to compile your project is now pretty simple. Create the
            following structure:
        </p>
        <pre class="sourceCode bordered">
<code>.
├── build.sbt
├── project
│   ├── build.properties
│   └── plugins.sbt
└── src</code></pre>
        <h2 id="build.sbt">build.sbt</h2>
        <pre class="sourceCode bordered"><code>name := "application"
version := "0.1"
enablePlugins(DottyPlugin)</code></pre>
        <h2 id="build.properties">build.properties</h2>
        <pre class="sourceCode bordered"><code>sbt.version=0.13.11</code></pre>
        <h2 id="plugins.sbt">plugins.sbt</h2>
        <pre class="sourceCode bordered"><code>addSbtPlugin("com.felixmulder" % "sbt-dotty" % "0.1.7")</code></pre>
        <p>
            This plugin is based on the
            <a href="https://github.com/smarter/dotty-example-project">
                dotty-example-project
            </a>, but let’s you skip building dotty from scratch.
