 By design, options (flags like `--name` or `-n`) are optional—that's why they're called "options." However, there are cases where you want a named option that users must provide, such as specifying a target environment or API key.

 ```
 OPTIONS:
-    -e, --environment    Target environment (Required)
-    -v, --version        Version to deploy (Required)
+    -e, --environment    Target environment. Required
+    -v, --version        Version to deploy. Required
