 Note that usage message is essential here, and it should not be empty.
 
+## Hidden flags
+It is possible to mark a flag as hidden, meaning it will still function as normal, however will not show up in usage/help text.
+
+**Example**: You have a flag named "secretFlag" that you need for internal use only and don't want it showing up in help text, or for its usage text to be available.
+```go
+// hide a flag by specifying its name
+flags.MarkHidden("secretFlag")
+```
