I had recently purchased your basic humidor from www.cigar.com

my question to all who know more than me is what do i need to do with it.
It came with a humidifier, but no instructions. I do not know if i need to add any of those crystals or to add water. I decided its best to do nothing until properly instructed to do so...

any input would be greatly appreciated.
thanks for your time
