tile install and concrete slab cracks

I'd like to install tile in the kitchen but have several cracks in the slab (removed vinyl tiles). I'll fill them but was wondering what can I do before install in case other cracks develop later on after tile is installed. Have installed crack isolation membrane befrore but only over visible cracks. I'm worried other cracks may develop over time. I've heard about a "slipsheet"--what is it and/or what are some recommedations? Thanks

Use a crack isolation membrane over the entire floor.

Doe any of the cracks show signs of vertical movement - one side of the crack higher than the other. If so, nothing will fix this and you should use a different floor covering than ceramic tile. If no vertical movement you should be ok using the membrane.

Slip sheet won't help here.
