 ## Quick Start
 
 This section describes how to run YCSB on MongoDB. 
 
 ### 1. Start MongoDB
 
 First, download MongoDB and start `mongod`. For example, to start MongoDB
 on x86-64 Linux box:
 
     wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-x.x.x.tgz
     tar xfvz mongodb-linux-x86_64-*.tgz
     mkdir /tmp/mongodb
     cd mongodb-linux-x86_64-*
     ./bin/mongod --dbpath /tmp/mongodb
 
 Replace x.x.x above with the latest stable release version for MongoDB.
 See http://docs.mongodb.org/manual/installation/ for installation steps for various operating systems.
 
 ### 2. Install Java and Maven
 
 Go to http://www.oracle.com/technetwork/java/javase/downloads/index.html
 
 and get the url to download the rpm into your server. For example:
 
     wget http://download.oracle.com/otn-pub/java/jdk/7u40-b43/jdk-7u40-linux-x64.rpm?AuthParam=11232426132 -o jdk-7u40-linux-x64.rpm
     rpm -Uvh jdk-7u40-linux-x64.rpm
     
 Or install via yum/apt-get
 
     sudo yum install java-devel
 
 Download MVN from http://maven.apache.org/download.cgi
 
     wget http://ftp.heanet.ie/mirrors/www.apache.org/dist/maven/maven-3/3.1.1/binaries/apache-maven-3.1.1-bin.tar.gz
     sudo tar xzf apache-maven-*-bin.tar.gz -C /usr/local
     cd /usr/local
     sudo ln -s apache-maven-* maven
     sudo vi /etc/profile.d/maven.sh
 
 Add the following to `maven.sh`
 
     export M2_HOME=/usr/local/maven
     export PATH=${M2_HOME}/bin:${PATH}
 
 Reload bash and test mvn
 
     bash
     mvn -version
 
 ### 3. Set Up YCSB
 
 Download the YCSB zip file and compile:
 
-    wget https://github.com/achille/YCSB/archive/master.zip
-    unzip master
-    cd YCSB-master
+    git clone git://github.com/brianfrankcooper/YCSB.git
+    cd YCSB
     mvn -pl com.yahoo.ycsb:core,com.yahoo.ycsb:mongodb-binding clean package
 
 ### 4. Run YCSB
     
 Now you are ready to run! First, load the data:
 
     ./bin/ycsb load mongodb -s -P workloads/workloada > outputLoad.txt
 
 Then, run the workload:
 
     ./bin/ycsb run mongodb -s -P workloads/workloada > outputRun.txt
 
 See the next section for the list of configuration parameters for MongoDB.
