+In short, why did I create this library?
 
 1. It's faster than `filepath.Walk`.
 1. It's more correct on Windows than `filepath.Walk`.
 1. It's more easy to use than `filepath.Walk`.
 1. It's more flexible than `filepath.Walk`.
 
+Depending on your specific circumstances, [you might no longer need a
+library for file walking in
+Go](https://engineering.kablamo.com.au/posts/2021/quick-comparison-between-go-file-walk-implementations).
