+## Quick Start
+
+This section describes how to run YCSB on a MapR Cluster against MapR-DB (Binary).
+
+### 1. Set Up YCSB
+
+Clone the YCSB git repository and compile:
+
+ git clone https://github.com/brianfrankcooper/YCSB.git
+ cd YCSB
+ mvn clean package
+
+### 2. Create MapR-DB Binary Table
+
+ maprcli volume create -name tables -path /tables
+ maprcli table create -path /tables/myTable
+ maprcli table cf create -path /tables/myTable -cfname cf0
+
+### 3. Run YCSB
+
+###### 3.1. Load Table
+
+ ./bin/ycsb load maprdb -P workloads/workloada -cp $(mapr classpath) -p table=/tables/myTable -p columnfamily=cf0
+
+###### 3.2. Run workload
+
+ ./bin/ycsb run maprdb -P workloads/workloadb -cp $(mapr classpath) -p table=/tables/myTable -p columnfamily=cf0
