 ```
-**3 [Create an Android project](https://developer.android.com/training/basics/firstapp/creating-project.html) under your working directory.**
+**3 Prepare the app**
 - Set Application name to "Helloworld Example" and set Company Domain to "grpc.io". Make sure your package name is "io.grpc.helloworldexample"
 - Choose appropriate minimum SDK
 - Use Blank Activity
 - Set Activity Name to HelloworldActivity
 - Set Layout Name to activity_helloworld
 **4 Prepare the app**
 - Clone this git repo
 ```sh
 $ git clone https://github.com/grpc/grpc-common
 ```
 - Replace the generated HelloworldActivity.java and activity_helloworld.xml with the two files in this repo
 - Copy GreeterGrpc.java and Helloworld.java under your_app_dir/app/src/main/java/io/grpc/examples/
 - In your AndroidManifest.xml, make sure you have
 ```sh
 <uses-permission android:name="android.permission.INTERNET" />
 ```
 added outside your appplication tag
-**5 Add dependencies. gRPC Java on Android depends on grpc-java, protobuf nano, okhttp**
+**4 Install the app**
 - Copy grpc-java .jar files to your_app_dir/app/libs
 ```sh
 $ cp grpc-java/core/build/libs/*.jar your_app_dir/app/libs/
 $ cp grpc-java/stub/build/libs/*.jar your_app_dir/app/libs/
 $ cp grpc-java/nano/build/libs/*.jar your_app_dir/app/libs/
 $ cp grpc-java/okhttp/build/libs/*.jar your_app_dir/app/libs/
 ```
 - Copy or download other dependencies to your_app_dir/app/libs/
  - [Guava 18](http://search.maven.org/remotecontent?filepath=com/google/guava/guava/18.0/guava-18.0.jar)
  - [okhttp 2.2.0](http://repo1.maven.org/maven2/com/squareup/okhttp/okhttp/2.2.0/okhttp-2.2.0.jar)
  - [okio](http://search.maven.org/remotecontent?filepath=com/squareup/okio/okio/1.2.0/okio-1.2.0.jar)
  - [jsr305](http://search.maven.org/remotecontent?filepath=com/google/code/findbugs/jsr305/3.0.0/jsr305-3.0.0.jar)
  - protobuf nano:
 ```sh
 $ cp ~/.m2/repository/com/google/protobuf/nano/protobuf-javanano/3.0.0-alpha-2/protobuf-javanano-3.0.0-alpha-2.jar your_app_dir/app/libs/
 ```
 - Make sure your_app_dir/app/build.gradle contains:
 ```sh
-dependencies {
+$ cd grpc-common
-    compile fileTree(dir: 'libs', include: ['*.jar'])
+$ ./gradlew installDebug
 }
