+
+**A parser for URNs**.
+
+> As seen on [RFC 2141](https://tools.ietf.org/html/rfc2141#ref-1).
+
+[API documentation](https://godoc.org/github.com/leodido/go-urn).
+
+## Installation
+
+```
+go get github.com/leodido/go-urn
+```
+
+## Performances
+
+This implementation results to be really fast.
+
+Usually below ½ microsecond on my machine<sup>[1](#mymachine)</sup>.
+
+Notice it also performs, while parsing:
+
+1. fine-grained and informative erroring
+2. specific-string normalization
+
