How to install the UnderlineMe extension?

Head over to the Chrome Webstore and install UnderlineMe. Login with your UnderlineMe account or signup for a new account from the Dashboard.

How do I access my notes?

Right click on the extension icon and click on 'All Notes'. This will take you to your Dashboard from where you can browse your notes.

Does it support sync between browsers

Yes it does.
For instance, if you're on your work laptop and take some annotations - then head home and open up your personal laptop, your annotations will be there. Sync is now fully supported. You can now annotate notes via different devices and they will be kept in sync.
The dashboard is also kept in sync so whenever you edit your notes, the dashboard will update automatically.

How to take annotations on PDFs?

Open any PDF file hosted online. Example. Now click on the UnderlineMe extension icon and a new pdf viewer will open. You can start annotating text from here.

The reason why we can't have the annotation popup running on the browser's PDF viewer is because extensions can't run on that page. You'll notice the same issue with other similar extensions.

Can I do drawings on pages?

No that's not supported. Kami extension is a decent alternative if you want drawing support.
