Most users will be able to navigate and use ving without any issues or introduction while others might require a short introduction.
Below is a video you can share with them so they understand how to use Ving.
Here is some sample text that you might send out to your viewers.
"Hi Team, We are getting ready to send you training and other communications through a new tool called Ving. Please do not disregard the messages coming from this new platform."
From here you can customize your intro email or communication to include the personalized settings. For example: if you are using microburst settings let them know, "We will be requiring that you do at least 5 minutes of training a day. The system will navigate you away and invite you back with reminders until you finish.
