 A Markdown renderer for Vapor and Leaf. This uses the [Vapor Markdown](https://github.com/vapor/markdown) package to wrap [cmark](https://github.com/jgm/cmark) (though a [fork](https://github.com/brokenhandsio/cmark-gfm) is used to make it work with Swift PM), so it understands [Common Mark](http://commonmark.org). A quick reference guide for Common Mark can be found [here](http://commonmark.org/help/).

+To add the tag to Leaf, add it to your `LeafTagConfig`:
 
 ```swift
-if let leaf = drop.view as? LeafRenderer {
-    leaf.stem.register(Markdown())

+try services.register(LeafProvider())
+var tags = LeafTagConfig.default()
+tags.use(Markdown(), as: "markdown")
+services.register(tags)
 ```
 
-Don't forget to import MarkdownProvider in the file you register the tag or add the provider in with `import MarkdownProvider`
+**Note:** it's important that you register the `LeafProvider` first otherwise this will override your `LeafTagConfig`.

+Don't forget to import LeafMarkdown in the file you register the tag with `import LeafMarkdown`.
