There was no advice provided other than to "look it up". That's not particularly helpful for someone new to the field and overwhelmed by the amount of resources and approaches. If you are aware of "documentation" it would be more useful to provide links to such resources for someone just getting started.

A solid resource for me getting started was the textbook Probabilistic Robotics. It may not be state of the art but I feel it is a great resource on the topic -
