A Quakers Guide to Online Worship and Meetings
Here is an excellent resource on virtual Quaker Meetings from Woodbrooke, in England.
This is very long and detailed, but has a good index and you can just read the parts that are pertinent to your needs. For example, you don't have to read all the sections about how to connect with different operating systems and devices, just the one you use. If you are not opening, closing, or hosting a meeting you don't have to read those sections, either.
Here are some more pages of useful information from Woodbrooke for newcomers to online Worship:
