 [![Build Status](https://magnum.travis-ci.com/testfairy/testfairy-android-studio-plugin.svg?token=dEpogdhSnM976NXR45qA&branch=master)](https://magnum.travis-ci.com/testfairy/testfairy-android-studio-plugin)
 
+## Requirements
+TestFairy Integration intellij plugin has been tested on IDEA 13 and Android Studio 1.1+ (Android Studio will be used in further text for brevity).
+
+It is based on [TestFairy plugin for Gradle](https://github.com/testfairy/testfairy-gradle-plugin),
+so it requires a Gradle based Android application module.
+
+At the moment, we only support Android Studio projects with settings.gradle in project root
+and Android application module included on its very first line.
+
+## Plugin Setup
+1. Download plugin installation from: [TestFairy Integration plugin releases](https://github.com/testfairy/testfairy-android-studio-plugin/releases)
+1. Go to Android Studio Preferences (Mac OS: Android Studio/Preferences; Others: File/Settings), and type Plugins.
+1. Click on 'Install plugin from disk...'.
+1. Locate the downloaded file and select it.
+
+## Usage
+To upload the android app to TestFairy, use Tools/TestFairy/Upload to TestFairy or click on TestFairy toolbar icon near the Build and Run buttons.
+
+The first time you do it, the plugin will prompt you for your IDE Master Password (if you have one) and TestFairy API key.
+After that, your project will be configured for integrated uploads to TestFairy.
+
+In order to change TestFairy API key, you can always go to Tools/TestFairy/Settings.
+The plugin will always apply the most recently entered API key to your projects.
