+### Flask-API managing Users And Events
+
+A RESTful API that manages events, offering users the ability to schedule, retrieve,
+update, delete, and be reminded of events with additional advanced features.
+
+# Flask-API - Interface
+- The User Will be able to retrieve upcomming event/s
+  - sort by
+    - popularity
+    - date
+  - filter by:
+    - location
+- The User will be abale to create/update a new event
+- The User will be able to login/out
+- The User can `Attend`/`UnAttend` to an event
+- The Anonymous User will be able to create a new user
+
+- Event:
+  - (Auth Users) An event is an upcomming Party/Concert/Sport event/etc. It is tied to a user that created this event.
+
+- Authentication:
+  - The User will be able to login:
+    - The API will generate a JWT token and set the userId inside the Flask session.
+    - The API will return the JWT token in the response cookie header.
+
+# Backend-reminder
+- The Users will be able to be reminded of upcoming events.
+- The backend will Send reminders 30 minutes before the event's scheduled time.
+
+
+
+
+
+# Database
+ - Sqlite(for simplicity use)
+ # Schema
+  - User - 
+    - Id (UUID, primary key)
+    - Name (string, required)
+    - Email (string, required, unique)
+    - Password_hash (string, required)
+    - location (string, required)
+  - Event
+    - Id (int, primary key)
+    - Title (string, required)
+    - Description (string, required)
+    - Location (string, required)
+    - Deleted (bool, required)
+    - DueDate (string, required)
+    - User_id (string, required, foreign key)
+  
+  - User Event Association (Many to Many)
+    - User_id (string, required, foreign key)
+    - Event_id (Integer, required, foreign key)
+    - Notification Made (bool, required)
+
+
+# API EndPoints
+- GET /events (Optional: ?['location' = String, 'sort_by' = Enum('date'/'popularity'/'creation' ) ])
+- GET /events/{id} - returns a single event
+- POST /events - create a new event (Auth)
+- PUT /events/{id} - update an event (Auth + authorized)
+- DELETE /events/{id} - (Soft)delete an event (Auth +  authorized)
+
