+## Quick Start
+
+This section describes how to run YCSB on RADOS of Ceph.
+
+### 1. Start Ceph
+
+After you start your Ceph cluster, check your cluster’s health first. You can check on the health of your Ceph cluster with the following:
+
+    ceph health
+
+### 2. Install Java and Maven
+
+### 3. Set Up YCSB
+
+Git clone YCSB and compile:
+
+    git clone -b dev-ceph-rados https://github.com/jaemyoun/YCSB.git
+    cd YCSB
+    mvn -pl com.yahoo.ycsb:rados-binding -am clean package
+
+### 4. Configuration Parameters
+
+- `rados.configfile`
+  - The Path of Ceph configuration file
+  - Default is '/etc/ceph/ceph.conf'
+
+- `rados.id`
+  - The user ID to access to pools in order to read and write data
+  - Default is 'admin'
+
+- `rados.pool`
+  - The pool name to be used for the benchmark
+  - Default is 'data'
+
+Or, you can set configs with the shell command, EG:
+
+    ./bin/ycsb load rados -s -P workloads/workloada -p "rados.configfile=/etc/ceph/ceph.conf" -p "rados.id=admin" -p "rados.pool=data" > outputLoad.txt
+
+### 5. Load data and run tests
+
+Load the data:
+
+    ./bin/ycsb load redis -s -P workloads/workloada > outputLoad.txt
+
+Run the workload test:
+
+    ./bin/ycsb run redis -s -P workloads/workloada > outputRun.txt
