What little I know.
If you are not going to go 10 x 10 x 5 feet and water it and turn it every couple of months then you are better off putting the clippings straight on the garden as mulch. Then turn it under once a year when you turn your garden and add more mulch to the top as you cut the grass or collect the leaves. (Lasagna method I think I have heard it called) Good mulch will choke out weeds (or at least make them real easy to pull) and mulch will help keep the soil warm and moist. No turning the pile every couple of months, just spread it and forget it!
If you really want good compost to be able to fill in low spots in the yard or add to a new garden, you really have to work at it. There is more to it than pile it up in a corner and wait. There is supposed to be a good carbon to nitrogen balance of like 30:1, But I have never lived anywhere that has this perfect blend of yard waste it always seems like 150:1 all pine needles and or oak leaves and nothing with nitrogen.
There are books and courses all about composting and it is all about trying to speed up mother nature or help mother nature. I got some news for you, mother nature has been at it for a long time and no matter where we pile the stuff, it will break down, so why not just pile it where you want it to start with? The only catch is, time. If you are in a hurry , then you will need to work harder.
Working harder means turning and watering and building a pile big enough to heat or using a contraption of one sort or another and adding non-yardwaste stuffs to the pile and following one of a thousand different compost gurus ideas on how best to do things. And yes, almost all of these methods work, but they take extra work.
