How to get a free Sepolia faucet?

I'm curious, can you walk me through the steps to access a free Sepolia faucet? I've heard that it's a great way to get started with crypto, but I'm not sure where to begin. Are there any specific requirements or precautions I should be aware of before I dive in? Also, how reliable are these faucets, and can I trust that they'll actually deliver the promised cryptocurrency to my wallet? I'd appreciate any guidance you can offer.
