I am hoping to be forgiven for not knowing this, but the fact is experience levels vary and mine are not great as I have always used garage services.
Obviously I do know how to lift a corner to change a tyre.
But a different beast entirely is to lift the whole car on all 4 points, without having one of those platform lifts we see in any garage.
I understand the logic, I believe... Presumably by lifting one end first with an hydraulic jack and place 2 wide-base props (aka "Axle-Stands") under that end. Let the car rest on them and lower/remove the hydraulic jack. Then go to the opposite end, jack up that end and when level, shove another 2 wide-base Axle-Stands under that end. Then lower the jack to let that end rest on the props as was done for the first end.
But... And this is a big BUT (!), the devil might be in the detail, so what sounds fairly simple might actually be trickier and if we do not know the detail, we risk landing in hot water. The most obvious is the area needs to be flat and level. But that is nowhere near enough... Here are some examples:

The most obvious is the area needs to be flat and level. But that is nowhere near enough... Here are some examples:
- Where exactly in the middle does the hydraulic jack need to be to lift the whole end and stay balanced?
- Is there a dedicated support point to get the hydraulic jack to touch the under-chassis so the lift is safe and fully supported?
- Once one end is jack-lifted, where precisely should the axle-stands go? Should the far ends of the axle rest on them, or as wee in the garage, the 4 points near the wheel arches? Or are there 4 dedicated points to use?
- With one end already lifted, lifting the other end presumably equates to lifting the full weight of the car off the ground with a hydraulic jack positioned at the dead centre of the side we are going to lift, so now the precise point under the chassis the hydraulic jack lift point needs to touch is even more critical;
- The props or axle-stands positioning is also critical.
