How do I start?

Hello! I bought myself a Tarot deck some months ago to get started and do some physical readings and learn tarot, as I've always done it with some apps on my phone. It came with a little book that technically explains the meaning of every card, but the explanations are so brief I don't even understand it.

Could someone give me some advice on how to start with tarot? I've lost a lot of motivation because I don't know how to start or what to do, and I really wanna learn.

Any help or advice is really appreciated. Thank you!!! (My deck is Shadowscapes, just in case someone needs it to give proper advice or anything)
