+### What does this package do?
+
+This package provides a function (`valid?`) that allows to check and validate strings, based on different built-in schemes/patterns, e.g e-mails, urls, etc.
+
+### How do I use it?
+
+Simply `import` it and use the included `valid?` function:
+
+```arturo
+import "validator"!
+
+valid?.url "https://arturo-lang.io"
+; => true
+
+valid?.email "loremIpsum@
+; => false
+```
+
+> [!TIP]
+> Different type of checks may accept different extra params, so you'd better have a look into the reference first! :)
