+# MarkItUp Custom Element Example
+
+This is a simple demonstration of using [HTML Custom Elements](https://developer.mozilla.org/en-US/docs/Web/Web_Components/Using_custom_elements) in Elm.
+
+Inspired by [Luke Westby](https://github.com/lukewestby)'s [Elm Europe talk](https://youtu.be/tyFe9Pw6TVE). The JavaScript custom element code is almost a verbatim copy.
+
+To run it:
+
+* git clone and cd into the local copy
+* run `elm make src/Miu.elm --output js/miu-demo.js`
+* open "demo.html" in a web browser
