+# Installing Spark Standalone to a Cluster
+
+The easiest way to deploy Spark is by running the `./make-distribution.sh` script to create a binary distribution.
+This distribution can be deployed to any machine with the Java runtime installed; there is no need to install Scala.
+
+The recommended procedure is to deploy and start the master on one node first, get the master spark URL,
+then modify `conf/spark-env.sh` in the `dist/` directory before deploying to all the other nodes.
 
 # Starting a Cluster Manually
 
 You can start a standalone master server by executing:
 
-    ./spark-class org.apache.spark.deploy.master.Master
+    ./bin/start-master.sh
 
 Once started, the master will print out a `spark://HOST:PORT` URL for itself, which you can use to connect workers to it,
 or pass as the "master" argument to `SparkContext`. You can also find this URL on

 # Cluster Launch Scripts
 
-To launch a Spark standalone cluster with the deploy scripts, you need to create a file called `conf/slaves` in your Spark directory, which should contain the hostnames of all the machines where you would like to start Spark workers, one per line. The master machine must be able to access each of the slave machines via password-less `ssh` (using a private key). For testing, you can just put `localhost` in this file.
