+## Installation
+
+You will need:
+
+* Java 8
+* Gradle
+
+### Java
+
+If typing `java -version` on the command-line returns `command not found` or similar, then go to [java.com](https://www.java.com/en/download/help/index_installing.xml), which will tell you how to install Java on your system.
+
+If Java is already installed, you will see something like the following, perhaps with some extra details about builds and virtual machines:
+
+    java version "1.8.0"
+
+### Gradle
+
+On Mac OS X you can install Gradle using homebrew:
+
+    brew install gradle
+
+On Windows you will need to visit the [Gradle](http://gradle.org/installation) website and follow the instructions there.
+
+* Download the latest version (big green button)
+* Unpack the ZIP file, which will contain a folder (e.g. gradle-2.2.1)
+* Copy the folder to a convenient location
+* Add that location + `\bin` to your `PATH`
+
+Verify that it has been installed correctly by running:
+
+    gradle -version
+
+You should see a version number as well as some extra information about build time and dependencies.
