-This Go package provides an simple to use interface to the excellent 
-"[Have I Been Pwned](https://haveibeenpwned.com/API/v3)" (HIBP) API by Troy Hunt.
-
+This Go library provides simple and idiomatic bindings to the excellent 
+"[Have I Been Pwned](https://haveibeenpwned.com/API/v3)" (HIBP) API by Troy Hunt. It implements all 3 APIs
+that are provided by HIBP (Breaches, Pastes, Passwords). API key support for the private API endpoints are 
+supported as well.
 
 ## Usage
-Check out the [GoDocs Reference](https://pkg.go.dev/github.com/wneessen/go-hibp) for details on how to implement 
-access to the HIBP API with this package. You will also find GoDoc code examples there.
+The library is fully documented using the execellent GoDoc functionality. Check out the
+[GoDocs Reference](https://pkg.go.dev/github.com/wneessen/go-hibp) for details on how to implement 
+access to any of the 3 APIs with this package. You will also find GoDoc code examples there for each of those
+APIs.
