Embedding onto my web site

how do I get the code to embed the player into my website, please?

this is the Mixxx forum. Mixxx is a standalone DJ app for Linux, mac and Windows, not a flash or html5 player or some other web app…

So please can you tell me how my listeners can hear what I play?

Please learn about the broadcasting basics first
https://manual.mixxx.org/2.3/en/chapters/livebroadcasting.html
How to embed a player into your website depends on your streaming server/provider, not Mixxx.

Note this manual is about Mixxx 2.3 which is the version we’re about to release next days probably.
I doubt many details changed since 2.2.4, though.

Also check this thread in case you encounter a bug with libshout (the part of Mixxx responsible for connecting to your shoutcast/icecast server)

Thank you so much for your help, I will read that and see how I get on!
Bless you for taking the time to help me!
