+sanitized_anchor_name
+=====================
+
+[![Build Status](https://travis-ci.org/shurcooL/sanitized_anchor_name.svg?branch=master)](https://travis-ci.org/shurcooL/sanitized_anchor_name) [![GoDoc](https://godoc.org/github.com/shurcooL/sanitized_anchor_name?status.svg)](https://godoc.org/github.com/shurcooL/sanitized_anchor_name)
+
+Package sanitized_anchor_name provides a func to create sanitized anchor names.
+
+Its logic can be reused by multiple packages to create interoperable anchor names
+and links to those anchors.
+
+At this time, it does not try to ensure that generated anchor names
+are unique, that responsibility falls on the caller.
+
+Installation
+------------
+
+```bash
+go get -u github.com/shurcooL/sanitized_anchor_name
+```
+
+Example
+-------
+
+```Go
+anchorName := sanitized_anchor_name.Create("This is a header")
+
+fmt.Println(anchorName)
+
+// Output:
+// this-is-a-header
+```
