In short, to embed asciicast with id 123 you insert <script type="text/javascript" src="https://asciinema.org/a/123.js" id="asciicast-123" async></script> in the markup where you want the player to show up.

There lies the problem I faced, Discourse removes most script tags automatically so the player won't show up at all :frowning:

<script type="text/javascript" src="https://asciinema.org/a/123.js" id="asciicast-123" async></script>

(This post includes an [asciinema embed](https://meta.discourse.org/raw/20786/11) yet it doesn't show up)
