Requirements

#Summary

Our project aims to serve people to learn about what they are eating in terms of micro and macro nutrients. There will be two types of user; regular users and food servers. Food servers will enable to create a profile and description of the foods they serve. Regular users will be able to explore the servers, the food, and see the information about the food. They will also able to get the information about ingredients and calories of foods. Furthermore users will be able to tag, comment and rate food as well as the servers. The users will able to view their consumption history. They will also enable to share with other users as well as social media.
