Simplified peer dependencies
For 0.x versions, NPM uses a different setup for caret and tilde.
I really don't want to go to 1.0 just yet, but also want peer dependencies to be simple.
So I changed the instructions to use ">=0.20.0" i.s.o. "^0.20.0" because it will be ok for 1.x and further as well.
