+The following document is a step-by-step guide to run BWS in cluster mode.
+
+Configuration for all required modules can be specified in https://github.com/bitpay/bitcore-wallet-service/blob/master/config.js
+
+
+###Install BWS
+```bash
+npm install bws
+cd bws
+````
+
+###Start MongoDB
+Example configuration for connecting to the MongoDB instance:
+```javascript
+  storageOpts: {
+    mongoDb: {
+      uri: 'mongodb://localhost:27017/bws',
+    },
+  }
+```
+
+###Start locker service
+```bash
+node locker/locker.js
+````
+Example configuration for connecting to locker service:
+```javascript
+  lockOpts: {
+    lockerServer: {
+      host: 'localhost',
+      port: 3231,
+    },
+  }
+```
+
+###Start message broker service
+```bash
+node messagebroker/messagebroker.js
+````
+Example configuration for connecting to message broker service:
+```javascript
+  messageBrokerOpts: {
+    messageBrokerServer: {
+      url: 'http://localhost:3380',
+    },
+  }
+```
+
+###Configure blockchain service
+Note: this service will be used by blockchain monitor service as well as by BWS itself.
+An example of this configuration is:
+```javascript
+  blockchainExplorerOpts: {
+    livenet: {
+      provider: 'insight',
+      url: 'https://insight.bitpay.com:443',
+    },
+    testnet: {
+      provider: 'insight',
+      url: 'https://test-insight.bitpay.com:443',
+    },
+  }
+```
+
+
+###Start blockchain monitor service
+The monitor service is used to notify instances of BWS of incoming txs. It will connect to all previous services so it is important that those are already running.
+```bash
+node bcmonitor/bcmonitor.js
+````
+
+
+###Start email service
+```bash
+node emailservice/emailservice.js
+````
+Example configuration for connecting to email service (using postfix):
+```javascript
+  emailOpts: {
+    host: 'localhost',
+    port: 25,
+    ignoreTLS: true,
+    subjectPrefix: '[Wallet Service]',
+    from: 'wallet-service@bitcore.io',
+  }
+```
+
+###Enable clustering
+Change `config.js` file to enable and configure clustering:
+```javascript
+{
+  cluster: true,
+  clusterInstances: 4,
+}
+```
+
+###Start bws instances
+```bash
+npm start
+````
