+# Icinga Go Library
+
+The Icinga Go Library is a collection of Go packages used for common tasks in Icinga's Go applications.
+
+While some of these packages are only useful internally, others might be useful for extending Icinga applications.
+For example, the `notifications` package is designed for interoperability with [Icinga Notifications](https://github.com/Icinga/icinga-notifications).
+
+## Documentation
+
+The Go package documentation is available online at [pkg.go.dev/github.com/icinga/icinga-go-library](https://pkg.go.dev/github.com/icinga/icinga-go-library).
