 **Brief Description**:
-Our application is a finance tracker, so a person can easily track his cash flow
-through multiple bank accounts. Person can label transactions with custom categories
-and later filter by them.
+Our application allows users to easily track their cash flow
+through multiple bank accounts. Users can label their transactions with custom categories that can be later used for 
+filtering and visualization. New transactions are automatically fetched in the background.
 
 ## Architecture Overview
-Our system is a full‑stack web application composed of a React frontend, a FastAPI backend, a PostgreSQL database, and asynchronous background workers powered by Celery with RabbitMQ. Redis is available for caching/kv and may be used by Celery as a result backend. The backend exposes REST endpoints for authentication (email/password and OAuth), users, categories, and transactions. A thin controller layer (FastAPI routers) lives under app/api. Infrastructure for Kubernetes is provided via OpenTofu (Terraform‑compatible) modules and the application is packaged via a Helm chart.

 The workflow works in the following way:
 - Client connects to the frontend. After login, frontend automatically fetches the stored transactions from 
-the database via the backend API
+the database via the backend API and currency rates from UniRate API.
 - When the client opts for fetching new transactions via the Bank API, the backend delegates the task 
 to a background worker service via the Message queue.
 - After successful load, these transactions are stored to the database and displayed to the client

+### Features
+- The stored transactions are encrypted in the DB for security reasons.
+- For every pull request the full APP is deployed on a separate URL and the tests are run by github CI/CD
+- On every push to main, the production app is automatically updated

 ### Components
 
 - Frontend (frontend/): React + TypeScript app built with Vite. Talks to the backend via REST, handles login/registration, shows latest transactions, filtering, and allows adding transactions.
-- Backend API (backend/app): FastAPI app with routers under app/api for auth, categories, and transactions. Uses FastAPI Users for auth (JWT + OAuth), SQLAlchemy ORM, and Pydantic v2 schemas.

 - Worker service (backend/app/workers): Celery worker handling asynchronous tasks (e.g., sending verification emails, future background processing).
 - Database (PostgreSQL): Persists users, categories, transactions; schema managed by Alembic migrations.
 - Message Queue (RabbitMQ): Transports background jobs from the API to the worker.
