 First create a `logging.Client` to use throughout your application:
 [snip]:# (logging-1)
+
 ```go
 ctx := context.Background()
 client, err := logging.NewClient(ctx, "my-project")
 if err != nil {
-	// TODO: Handle error.
+   // TODO: Handle error.
 }
 ```
 
 Usually, you'll want to add log entries to a buffer to be periodically flushed
 (automatically and asynchronously) to the Cloud Logging service.
 [snip]:# (logging-2)
+
 ```go
 logger := client.Logger("my-log")
 logger.Log(logging.Entry{Payload: "something happened!"})
 ```
 
 Close your client before your program exits, to flush any buffered log entries.
 [snip]:# (logging-3)
+
 ```go
 err = client.Close()
 if err != nil {
-	// TODO: Handle error.
+   // TODO: Handle error.
 }
