+### tags
+
+There is preliminary support for tag style metadata per post.
+
+Add a "tags" field to your post preamble. Tags should be comma separated.
+
+```
+    tags: TagOne, tag two, a third tag, fourth
+
+```
+
+Tags will be normalized to lowercase, with spaces replaced with underscores. So the above would have tagged a post with --
+
+`tagone tag_two a_third_tag fourth`
+
+Tags are accessible in each post struct via the `Tags` field.
+
+To create archives of tags, create a template named `tags` -- it will behave the same as an `archive` template, but create a file at HTML_DIR/tag/tag_name/index.html for each unique tag.
