+This API serves as the backend for a Kanban-style project management application.
+It allows users to manage projects, tasks, and user assignments with proper authentication and authorization.
+
+## Stack
+- FastAPI
+- SQLAlchemy
+- SQLite
+
+## Features
+- User Authentication (JWT and Argon2 Password Hashing)
+- Project Management (Create, Read, Update, Delete)
+- Task Management within Projects
+- User Assignments to Projects
+- CORS Configuration for Frontend Integration
+
+## Source Code
+The source code for this API can be found on [GitHub](https://github.com/a-mayb3/Kanban_clone_backend) or [my forgejo instance](https://git.vollex.cc/a-mayb3/Kanban_clone_backend).
+
+## Other projects
