Scheduling a meeting and adding participants?

Hello,

I am new to Zoom and just watched the Zoom video on how to schedule a meeting. The video was quite thorough, but it did not cover how to add participants (in Web Portal). Do I need to setup the meeting on the Zoom Web Portal first then go into my calendar? I use MS Outlook for the calendar.

Thank-you in advance for any information or tips to add participants!
