 ## Why /vN in Module Paths?
 
-Go requires the `/vN` suffix in module paths for major versions greater than 1 to enable semantic versioning. This allows different major versions to coexist without conflicts, as each version is treated as a separate module. For example, `github.com/DakshithaS/go-multi-major-modules/rate-limit/v2` is distinct from `github.com/DakshithaS/go-multi-major-modules/rate-limit`.
