# Feed & NFTs

### Feed

This feature of the Dememoriam platform is the main area where users are exposed to content posted on the platform. Users can hear other people's stories or thoughts, subscribe, tip, and more. Feed is the place where all NFTs are uploaded, traded, viewed, and interacted with. The user can check other people's profiles and explore their content.

### How to buy NFTs

If the user explores the feed and finds any NFTs or owners that he likes, he can just click on the speaking avatar and purchase the item if it is on sale. If the user does not wish to purchase NFT but enjoys the content of other users' profiles, he may tip the other user in order to support his creations. The user must have Memory's wallet in order to buy or sell NFT on a tip.

### NFT Categories

On the Dememorium platform, users can view other people's NFTs and hear their stories. In order to specify what exact content they want to see, users can choose between 20 categories and hundreds of sub-categories, as well as use the search bar for key words.\
\
How do categories work?\
\
Every user, before creating an account, writes about his hobbies, occupation, and other personal information. Another way for the platform to find content is by entering keywords; each NFT has its own spoken story, and the speech script is stored in the Dememoriam back-end system, which can recover any sentence at any time.
