+# Basic sample for Robolectric
+
+*If you are new to Robolectric, try this sample first.*
+
+This project uses the Gradle build system. You don't need an IDE to build and execute it but Android Studio is recommended.
+
+1. Download the project code, preferably using `git clone`.
+1. In Android Studio, select *File* | *Open...* and point to the `./build.gradle` file.
+1. Check out the relevant code:
+    * The application under test is located in `src/main/java`
+    * Tests are in `src/test/java`
+1. Create the test configuration:
+    * Open *Run* menu | *Edit Configurations*
+    * Add a new *Android JUnit Tests* configuration
+    * Choose a module
+    * Set the working directory to the module directory.
+1. Run the newly created configuration
+
+If you are using Android Studio, the *Run* window will show the test results.
