+# CertChecker
+
+[![Go Reference](https://pkg.go.dev/badge/git.domandoman.xyz/doman/certchecker.svg)](https://pkg.go.dev/git.domandoman.xyz/doman/certchecker)
+
+CertChecker is VERY COMPLEX Go package providing one function and one cli interface.
+
+## What does it do?
+
+Package scans domain to check if it's certificate won't expire soon.
+
+One may ask why do we need such an package when even personal hobby projects use automatic certbot certificates management? Yes.
+
+## Including package
+
+```go
+import "git.domandoman.xyz/doman/certchecker"
+```
