+_Minimalist schema for sharing items in different games_
+
+[Backpack] is an inventory system to share items between different games,
+for example:
+
+- Raise a crab in Crab Simulator,
+- Make it fight in Crab Shooter,
+- Cook it in Crab Cook...
+- Gain a crab skin in your favorite game!
+
+[Backpack] is in a pre-MVP state: a tech prototype is working.
+
+The project is not affiliated or related to Blockchain/NFTs:
+it uses a PostgreSQL DB to store users, games and items.
+Authentication is done via email/password,
+third party authentication via OAuth will be a future goal.
+An Authenticated user can create apps and add item definitions to these.
+Other users can get an independant instance of that item and modify its data.
+
+The next project milestone is
+2 minimalist interconnected games released by the end of 2023.
