 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.
+The ```defer client.Shutdown()``` line is for disconnecting the connection to our Bitcoin node from the rpcclient, once the ```main()``` function finishes executing. After the ```defer client.Shutdown()``` line is where the exciting stuff is, like ```client.GetBlockCount()``` and ```client.GetBlockHash(blockCount)```.
+
+The rpcclient functions can take inputs as well, for example ```client.GetBlockHash(blockCount)``` takes the block count as an input. The ```client.GetBlockHash(blockCount)``` from above would look like this as a ```bitcoin-cli``` command:
+
+```
+$ bitcoin-cli getblockhash 1773561
+00000000000000346bab4126f418a5820692c9a7de7ef79717bebfccebacad61
+```
 
 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()```.
