### Proposal
We would like to add getting started videos which we can link from the product and our documentation.
* Showcase typical workflows
* How to build out jobs
* Keyword examples
Also, there are some videos which are available today in our docs
* Should we keep them the way they are?
* Add a video section in our doc?
* Provide links from the product to the videos?
