Step 1. Add Revshare.js

Add a script tag in your head, referencing either the script in the node_modules dist folder, or the unpkg CDN.

<script src="https://unpkg.com/@kewbish/revshare"></script>

Step 2. Add a <rev-share> element

Add a rev-share tag. Required is a pointers attribute, which will include a JSON-formatted mapping of wallet to percentage pointer

<rev-share pointers='[{"$bob.wallet": 50, "$alice.wallet": 50}]'>
    ...
</rev-share>

Step 3. Sit back, and relax.

Revshare.js will take care of adding, updating, and removing payment pointers. It's based on the probablistic rev-share model outlined on the Web Monetization page.
