+### How to share a presentation in Zoom
+
+At some point, you may need to give a slide presentation using Zoom. Ideally, you should be able to see your speaker notes while participants see your slide show. This is fairly easy to do with two monitors by using presenter view and sharing the monitor which contains the slides. If you have only one monitor, it is still possible using the following steps:
+
+- Open your slide deck in google slides. Make sure to close any other tabs you may have open, participants will be able to see these tabs when it comes time to present.
+
+- Select `Presenter view`. This will make your presentation take up the entire screen.
+
+- Hover near the bottom of your presentation and you will see a pop up menu. From this menu, select the `Toggle Full Screen` option, third button from the right, next to settings. This will end full screen mode without leaving the presenter view.
+
+- To see your speaker notes, hover at the bottom of your presentation window again and select `Presenter View` from the menu.
+
+- You will now have a presenter view pop-up window which allows you to see your speaker notes as well as advance the slides.
+
+- In another browser window, enter the Zoom meeting room
+
+- Once in the meeting, select `Share Screen` from the options at the bottom of the screen.
+
+- Do not share your desktop. From the options, select the browser window containing your google slide deck. This will allow you to share just the browser window containing your slides. 
+
+- If you would also like to see the Zoom chat, hover your cursor at the top of the screen containing your Zoom meeting. A menu will appear, from this menu select More > Chat.
+
+- Position the windows any way you need to see the presentation and speaker notes.
+
+- Make sure to change slides using the presenter view pop up window. This will advance the presentation for your viewers as well as advancing your speaker notes.
+
+If you would like to practice presenting, you can do so using your own private Zoom room. 
+
+- Open the Zoom app and click `Start with video`
+
+- Click `Record`
+
+- Repeat the steps above
+
+- Stop and watch the recording. You'll see what the participants would see.

 ### Do NOT Use
 **Flash**: Due to security flaws, we strongly recommend _not_ using Adobe Flash. Certainly do not install it on your local machine. But even the Google Chrome plugin that let's you see embedded Flash content in websites can pose a security hazard. If you have not already, go to your [Chrome plugins](chrome://plugins) and disable Flash. For further context, note that [Google Chrome is removing Flash support soon](https://nakedsecurity.sophos.com/2016/05/18/yet-more-bad-news-for-flash-as-google-chrome-says-goodbye-sort-of/), and while the [plugin is better than a local install of Flash](http://security.stackexchange.com/questions/98117/should-flash-be-disabled-or-are-sandboxes-secure-enough), it still leaves vulnerabilities for [zero-day attacks](http://www.pctools.com/security-news/zero-day-vulnerability/).
