To Install arctic-web, simply add this line of code to your HEAD.
<script src="https://cdn.jsdelivr.net/npm/arcticweb@latest/index.js"></script>It's important to import this script tag before your other scripts otherwise your scripts cannot access arctic.
To authenticate a user simply call arctic.authenticate(app, callback), where app is your appID and callback is the URL the user should be redirected to when he's authenticated. The URL should led to an express app in which arctic-node is installed, so that the user information can be parsed
