How do I sell on the neighborhood app?

Excuse me, I was wondering if you could help me understand the process of selling items on the neighborhood app? I've heard it's a convenient way to connect with people in my community and get rid of unwanted items, but I'm not quite sure how to go about it. Could you please walk me through the steps, from creating a listing to finalizing the sale? Any tips or advice you have for making the most of the platform would also be greatly appreciated. Thank you in advance for your help!
