I've had pretty good luck so far with their yeast, and like the strains I've used. I don't remembering the company's directions being written on the can, so I looked it up on their site - it says to turn the can upside down in the fridge the night before use. At pitching, invert the can back upright and GENTLY crack the pull tab to fully vent any pressure (like you would a can of soda that got shaken). After opening, swirl the can to bring the yeast all into suspension, and dump.
Hopefully this is of some help in the future. If it's not printed on the can, it really should be.
