+> :warning: This package is deprecated, BTCPay Server is exposing a new, more complete and easy to use API called `Greenfield`. [Check the doc](https://docs.btcpayserver.org/Development/GreenFieldExample/)
+
 # node-btcpay
 
 ## Install
 ```shell
-npm install https://github.com/tanjalo/node-btcpay
+npm i btcpay
 ```
 
+## Private key generation
+* Generate and save private key:
+```bash
+$ node -p "require('btcpay').crypto.generate_keypair().getPrivate('hex')"
+XXXXXXXXXXXXXXXXXXXXX
+```
+
+Store the printed value in a safe place, e.g. environment variables
 
 ## Pairing
-* Generate and save private key:
-```js
-let btcpay = require('btcpay')
-var keypair = btcpay.crypto.generate_keypair()
-```
-* Create client:
-```js
-var client = new btcpay.BTCPayClient('https://btcpayserverhostname', keypair)
-```
+
+After generating your private key, you have to pair your client with your BTCPay store:
+
 * On BTCPay Server > Stores > Settings > Access Tokens > Create a new token, (leave PublicKey blank) > Request pairing
 * Copy pairing code:
 * Pair client to server and save returned token:
-```js
-client.pair_client(<pairing-code>).then(res => console.log(res))
->>> { merchant: '6gi59fB1LKxHuyY29m8tR6tRysWppk9TnuoM7wT77Las' }
-```
-* Recreate client:
-```js
-var client = new btcpay.BTCPayClient('https://btcpayserverhostname', keypair, {merchant: '6gi59fB1LKxHuyY29m8tR6tRysWppk9TnuoM7wT77Las'})
+
+```bash
+# Replace the BTCPAY_XXX envirnoment variables with your values and run:
+
+$ [space] BTCPAY_URL=https://mydomain.com/ BTCPAY_KEY=... BTCPAY_PAIRCODE=... node -e "const btcpay=require('btcpay'); new btcpay.BTCPayClient(process.env.BTCPAY_URL, btcpay.crypto.load_keypair(Buffer.from(process.env.BTCPAY_KEY, 'hex'))).pair_client(process.env.BTCPAY_PAIRCODE).then(console.log).catch(console.error)"
+
+# (prepend the line with a space to prevent BTCPAY_KEY from being saved to your bash history)
+
+>>> { merchant: 'XXXXXX' }
 ```
 
+Store the value of "merchant" in a safe place, e.g. environment variables
 
-## Creating a client
+## Recreating a client
+After pairing your client to the store, you can recreate the client as needed and use it in your code
 ```js
-var client = new btcpay.BTCPayClient('https://btcpayserverhostname', keypair, {merchant: '6gi59fB1LKxHuyY29m8tR6tRysWppk9TnuoM7wT77Las'})
+const btcpay = require('btcpay')
+const keypair = btcpay.crypto.load_keypair(new Buffer.from(<PRIVATEKEY>, 'hex'))
+
+// Recreate client
+const client = new btcpay.BTCPayClient(<BTCPAYURL>, keypair, {merchant: <MERCHANT>})
 ```

-## Get rates
+### Get rates
+Fetches current rates from BitcoinAverage (using your BTCPayServer)
 ```js
-client.get_rates('BTC_USD').then(rates => console.log(rates))
+client.get_rates(['BTC_USD'], <STOREID>)
+  .then(rates => console.log(rates))
+  .catch(err => console.log(err))
+```
+The first argument accepts a comma-separated list of currency pair.
+
+### Create invoice
+See [BitPay Invoice API documentation](https://bitpay.com/api#resource-Invoices)
+```js
+client.create_invoice({price: 20, currency: 'USD'})
+  .then(invoice => console.log(invoice.url))
+  .catch(err => console.log(err))
 ```
 
-The first argument accept comma-separated list of currency pair.

-## Create invoice
-See BitPay API documentation: https://bitpay.com/api#resource-Invoices
+### Get invoice

+  .then(invoice => console.log(invoice.status))
+  .catch(err => console.log(err))
 ```
-
-
-## Get invoice
-```js
