Hey Kirby community.
I’ve created a very simple plugin to add a HTML5 <audio> element with a kirbytag. Simply use (audio:audiofile.mp3) and you are done!
It can also be customised with <source> elements and a lot of attributes.
I’ve build it because I didn’t find any other one that was answering this need! I Hope I didn’t duplicate any other plugin. And I’ll be really glad if anyone find it usefull. 
Have a great day!
Wizhou.
