Multiclassing Question: Storm Sorc with Lvl-dip into Druid

Mostly going for a certain theme with my PC, I am considering rolling a Storm Sorc with a single level dip into Druid @ 2nd level (Sorc:19/Druid:1). I am not sure how exactly this effects my spell slots, and my spell progression. The multiclassing rules for spell-slots are confusing to me.

Can anyone explain this simply to me? or perhaps if you tell me what my spell-slots look like at both 2nd and then 3rd PC levels I will understand better.
