Modern Pages is customized with web parts, and in his first
demo, Peter shows how you can use some of them.
In the second demo Peter creates a modern page and makes
it the homepage of the site collection. The default team
site home page is a wiki page, but it can easily be replaced
with a modern page.
The Quick Links web part
In the third demo, Peter shows how you can use the Quick
Links web part. With this web part, you can link to documents
and pages and have a preview of the source. You can also
link to other websites, but that does not give a preview.
