I'm confused by the interpretation of the charging and discharging formulas:

Charging: Q= Qo (1-e^-t/RC)

Discharging: Q=Qoe^(-t/RC)

Like for Qo, like apparently its the max charge, so does that mean at the very end of charging? Initially, i thought that Qo meant that the initial charge (obviously it can't be zero...) but then for the Qo in discharging, what does that one mean? Like apparently it's the initial charge, do they mean the max charge of the capacitor at the end of charging?

And also, for the current formula for charging I(t)=Ie^-t/RC, does 'I' refer to the initial current that is maximum at the beginning of this process? And for the discharging one, i thought that there is no current at the beginning, but then in my book it says that I is the initial current in the circuit..are they referring to the charging current?

I know I'm really confused but any help would be much appreciated...
