To add Zoom as an extension to your browser, go to the link zoom.us/download.
Once you reach the site, scroll down until you find the “Extensions for Browsers” Section.

After you click the extension for chrome, you will be brought to a page to install the extension.

From there the extension will give you the option to “Schedule a Meeting” for a later date or “Start a Meeting” which will begin one instantly with whoever you’d like.

For further assistance with actually scheduling a meeting, attached is a great video from the Zoom support page. Click Here
