+
+The template function uses the [`SanitizedAnchorName` logic from Blackfriday](https://github.com/russross/blackfriday#sanitized-anchor-names).
+Since the same sanitizing logic is used as the markdown parser, you can determine the ID of a header for linking with anchor tags.
+
+```
+{{anchorize "This is a header"}} → "this-is-a-header"
+{{anchorize "This is also          a header"}} → "this-is-also-a-header"
+{{anchorize "main.go"}} → "main-go"
+{{anchorize "Article 123"}} → "article-123"
+{{anchorize "<- Let's try this, shall we?"}} → "let-s-try-this-shall-we"
+{{anchorize "Hello, 世界"}} → "hello-世界"
+```
