+
+Basics
+------------
+Make sure that you are using Java 8 or later. The output of `java -version`
+should contain `1.8`.
+
+
+Install Dotty
+-------------
+If you're a Mac user, you can install dotty with [brew](https://brew.sh/)
+
+```bash
+brew install lampepfl/brew/dotty
+```
+
+If you're a Linux or Windows user, download the [latest release](https://github.com/lampepfl/dotty/releases). Optionally add path of the folder `bin/` to the system environment variable `PATH`.
+
+Getting Dotty
+-------------
+```bash
+$ git clone --recursive https://github.com/lampepfl/dotty.git
+$ cd dotty
+$ sbt managedSources # Needed for IDE import to succeed
+```
+
+Dotty provides a standard sbt build: compiling, running and starting a repl can
+all be done from within sbt:
+
+```bash
+$ sbt
+> dotc tests/pos/HelloWorld.scala
+> dotr HelloWorld
+hello world
+```
+
+Try Dotty
+----------
+Try it in your browser with [Scastie](https://scastie.scala-lang.org/?target=dotty)
+
+
+Create a Dotty Project
+-----------------------
+The fastest way to create a new project in dotty is using [sbt (0.13.5+)](http://www.scala-sbt.org/)
+
+Create a dotty project:
+```bash
+$ sbt new lampepfl/dotty.g8
+```
+
+Or a Dotty project that cross compiles with Scala 2:
+```bash
+$ sbt new lampepfl/dotty-cross.g8
+```
+
+For an example project, see the [Dotty Example Proejct](https://github.com/lampepfl/dotty-example-project)
+
+
+Bash Scripts
+-------------
+Assuming that you have cloned the Dotty repo locally, append the following line on your `.bash_profile`:
+
+```shell
+$ export PATH=$HOME/dotty/bin:$PATH
+```
+
+and you will be able to run the corresponding commands directly from your console:
+
+```shell
+# Compile code using Dotty
+$ dotc tests/pos/HelloWorld.scala
+
+# Run it with the proper classpath
+$ dotr HelloWorld
+```
+
+
+Starting a REPL
+----------------
+```bash
+$ sbt
+> repl
+Welcome to Scala.next (pre-alpha)  (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_101).
+Type in expressions to have them evaluated.
+Type :help for more information.
+scala>
+```
+
+or via bash:
+
+```bash
+$ dotr
+```
