Mulching a garden?

Not sure if this is the best sub forum for this question. I am relatively new to permaculture principals but I have been aggressively bitten by the bug and most of what I am learning makes great sense to me. I am currently enrolled in a PDC However I have questions about not tilling my garden and going with a mulch instead. I am super visual so if anyone has a link to a vid or a good book on the subject that would be great. I am mostly concerned with working the soil and planting in the spring.....?

Thanks

This seems like what you are looking for.

I mulched part of our garden this year with shredded leaves and it did fantastic

I really like mulch. I do. I really do. But wow, so do the voles, and they are herbivores.....
