I got a keg of cider half way done that was pretty simple yet so delicious if you like a little sweeter cider.
for a 4 gallon batch, I added some honey and brown sugar and yeast for primary. gravity got down to 1.004 after 2 months. Then I backsweetened with brown sugar, frozen apple juice concentrate, and spices. The spices were cinnamon (liquid extract), vanilla (liquid extract), cloves, and allspice.
Message me if you want more details, but all you need to do is add a little extra sugar to boost the sugar concentration and then add yeast to get it going, worry about spices and backsweetening in a few months
