+## Coinbene Exchange
+
+### Current Features
+
++ REST Support
++ Websocket Support
+
+### How to enable
+
++ [Enable via configuration](https://github.com/thrasher-corp/gocryptotrader/tree/master/config#enable-exchange-via-config-example)
+
++ Individual package example below:
+
+```go
+  // Exchanges will be abstracted out in further updates and examples will be
+  // supplied then
+```
+
+### How to do REST public/private calls
+
++ If enabled via "configuration".json file the exchange will be added to the
+IBotExchange array in the ```go var bot Bot``` and you will only be able to use
+the wrapper interface functions for accessing exchange data. View routines.go
+for an example of integration usage with GoCryptoTrader. Rudimentary example
+below:
+
+main.go
+```go
+var c exchange.IBotExchange
+
+for i := range bot.exchanges {
+  if bot.exchanges[i].GetName() == "Coinbene" {
+    c = bot.exchanges[i]
+  }
+}
+
+// Public calls - wrapper functions
+
+// Fetches current ticker information
+tick, err := c.GetTickerPrice()
+if err != nil {
+  // Handle error
+}
+
+// Fetches current orderbook information
+ob, err := c.GetOrderbookEx()
+if err != nil {
+  // Handle error
+}
+
+// Private calls - wrapper functions - make sure your APIKEY and APISECRET are
+// set and AuthenticatedAPISupport is set to true
+
+// Fetches current account information
+accountInfo, err := c.GetAccountInfo()
+if err != nil {
+  // Handle error
+}
+```
+
++ If enabled via individually importing package, rudimentary example below:
+
+```go
+// Public calls
+
+// Fetches current ticker information
+ticker, err := c.GetTicker()
+if err != nil {
+  // Handle error
+}
+
+// Fetches current orderbook information
+ob, err := c.GetOrderBook()
+if err != nil {
+  // Handle error
+}
+
+// Private calls - make sure your APIKEY and APISECRET are set and
+// AuthenticatedAPISupport is set to true
+
+// GetUserInfo returns account info
+accountInfo, err := c.GetUserInfo(...)
+if err != nil {
+  // Handle error
+}
+
+// Submits an order and the exchange and returns its tradeID
+tradeID, err := c.Trade(...)
+if err != nil {
+  // Handle error
+}
+```
+
+### How to do Websocket public/private calls
+
+```go
+  // Exchanges will be abstracted out in further updates and examples will be
+  // supplied then
+```
