 This section explains how to interact with `bitcoind` using the Go programming language and the [btcd rpcclient](https://github.com/btcsuite/btcd/tree/master/rpcclient). Note that it has some quirks and some limitations.

 ## Building Your Connection
 
-With some programming languages, you'll need to do the work of managing RPC calls yourself. And, in Go, you will have to build your RPC connection:
+Every `bitcoind` function in Go begins with creating the RPC connection, using the `ConnConfig` function:
 ```
 	connCfg := &rpcclient.ConnConfig{

- The ```connCfg``` parameters allow you to choose the Bitcoin RPC port, username, password and whether you are on testnet or mainnet. Using ```rpcclient.New(connCfg, nil)``` we configure ```client``` to connect to our Bitcoin node.

- The ```defer client.Shutdown()``` line is for disconnecting from our Bitcoin node, once the ```main()``` function finishes executing. After the ```defer client.Shutdown()``` line is where the exciting stuff is — and it's to use. That's's because `rpcclient` helpfully turns the `bitcoin-cli` commands into functions using PascalCase. For example, ```bitcoin-cli getblockcount``` is ```client.GetBlockCount``` in Go.
