You can always jump into your pin-less conference room and start an ad-hoc meeting, but usually, you'll schedule meetings in advance.
Using our Chrome Extension, this is really simple to do! When you create an event in your Google Calendar, a new option will appear.
Click Make this a Jiminny meeting and your conference details will be inserted into the meeting invite. What's more, this will be synced with Jiminny so when the meeting starts you'll see the title.
