Zoom Client

[keggers2]

I am an online higher ed instructor. Although I have been using the college's Zoom for years, I have just created my own private account. It looks like it's all set up and I've been adjusting settings, profile, etc. but see that the Getting Started information references downloading Zoom Client. Do I need to do this? Why? Or have I already downloaded it somehow? Clearly I'm a newbie!
