Create a new model from a mode,

Newbie question for sure. I was playing with the confluence loader, as I want to create a question answering chat bot. It will be aware of all the data in our confluence.

I can just load a few pages and pass the to the model, but if I have thousands of pages, that’s not feasible to do it for each question.

I know I can load a pretrained model, and save as a new model. But how do I actually “teach” this model on the data I want, and next step, is how I update the trained data if something changed
