currency / exchange rate / imports / exports

Can anyone please explian briefly the relationship between Currency appreciation / deprec - exchange rate - exports / imports?

Domestic Currency depreciates --> less worth compared to foreign currency --> domestic products cheaper compared to imports --> more exports and less imports. It works the other way for appreciation. The dynamics are more complicated involving fiscal/monetary policy, economy growth, inflation, interest rates, balance of payments,… but you are not asking about them, so I do not explain them here.
