I want to help like minded people like you to kick start your journey in Cardano.
If you not already have some ADA laying around, you can head over to an exchange and buy some ADA with "real" money.
Get yourself either the Yoroi or Deadalus wallet.
Click in either of those on "recieve", copy the address and send ADA from the exchange to yourself.
In the Staking / Delegation section search for the ticker MUC (just like the munich airport) and hit delegate.
If you're not sure, please check the pool ID:
