 The btcd rpcclient works by calling bitcoin-cli commands through in PascalCase. For example, ```bitcoin-cli getblockcount``` is ```client.GetBlockCount``` in Go. 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 ```import``` declaration at the top allows you to import relevant libraries. For every example here we will need to import ```"log", "fmt" and "github.com/btcsuite/btcd/rpcclient"```. We may need to import additional libraries for some examples. ```log``` is used for printing out error messages. After each time our Bitcoin node is called, we have an if statement checking if there are any errors. If there are errors, ```log``` is used to print them out. ```fmt``` is used for printing out our output. Since the examples in this document have different libraries to import, I will be showing the entire Go file, not just the specific function.

+The ```defer client.Shutdown()``` line is for disconnecting the connection to our Bitcoin node from the rpcclient, once the ```main()``` function finishes executing.
 
 A quirk with hashes in rpcclient is that they will typically print in a different encoding if you were to print it normally with ```blockHash```. In order to print them as a string, we need to use ```blockHash.String()```.
