Would it be correct to state:

1. Matched impedance implies the antenna is matched to the transmission
line which is also matched to the source impedance

2. Matched impedance provides for maximum power transfer.

3. As impedance matching is optimised the SWR approaches 1:1

4. Matched impedance does not imply resonance.

5. Tuning for resonance is an attempt to tune to the sweat spot where
voltage swing at the antenna is maximised.

I have a rough idea how to impedance match (or I think i did)  but not sure
how to go about tuning for resonance. Any tips
