-BWS have a extensive test suite but have not been tested on production environments yet and have been recently released, so it it is still should be considered  BETA software.  
+BWS is been used in production enviroments for [Copay Wallet](https://copay.io), [Bitpay App wallet](https://bitpay.com/wallet) and others.

+# Getting Started
 ```
- npm install bitcore-wallet-service
- npm start
+ git clone https://github.com/bitpay/bitcore-wallet-service.git
+ cd bitcore-wallet-service && npm start
 ```
 
+
 This will launch the BWS service (with default settings) at `http://localhost:3232/bws/api`.
 
 BWS needs mongoDB. You can configure the connection at `config.js`
 
 BWS supports SSL and Clustering. For a detailed guide on installing BWS with extra features see [Installing BWS](https://github.com/bitpay/bitcore-wallet-service/blob/master/installation.md). 
 
+BWS uses by default a Request Rate Limitation to CreateWallet endpoint. If you need to modify it, check defaults.js' `Defaults.RateLimit`
+
+# Using BWS with PM2
+
+BWS can be used with PM2 with the provided `app.js` script: 
+ 
+```
+  pm2 start app.js --name "bitcoin-wallet-service"
+```
