If you have a pressure cooker, this is so easy. Once you do it, you will be asking yourself why it took you so long.
A couple more things-
You don't need to sterilize your jars or lids before filling, they do need to be clean. The whole lot (meat and all) will get sterilized in the pressure cooker (think home autoclave)
Dont worry about trimming every last piece of sinew, it will cook down to gelatin
Do use real canning jars, not old mayonnaise and the like. Canning jars are tempered so are less likely to break from thermal shock. Do check the jar rims for chips or cracks as they will not seal and the contents will spoil.
Add spices (if desired) and a bit of salt. I've used all sorts of things, onion, garlic, chipotle peppers, jalapeno slices. Season salt, Tony Charcharis, black pepper.. you get the idea.
