+### Gradle
+
+The build system is based on Gradle. There are several methods for setting Gradle up:
+
+* It can be downloaded from [the Gradle website](http://www.gradle.org/downloads).
+
+* Most distributions will have Gradle packages. Be careful to check the provided version; Debian and Ubuntu have old versions in their main repositories. There is a [PPA](https://launchpad.net/~cwchien/+archive/gradle) for Ubuntu with the latest version of Gradle.
+
+* A Gradle wrapper is provided in the codebase. It takes all the same commands as the regular `gradle` command. The first time that any command is run, it will automatically download, cache and use the correct version of Gradle. This is the simplest way to get started with the codebase. To use it, replace `gradle` with `./gradlew` (or `./gradlew.bat` on Windows) in the commands below.
+
+Gradle will pull dependencies over the clearnet by default. To use Tor, create a `gradle.properties` file in `i2p.android.base` containing:
+
+    ```
+    systemProp.socksProxyHost=localhost
+    systemProp.socksProxyPort=9150
