 **Brief Description**:
-[2-3 sentences describing what your application does and its main purpose]
+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.
 
 ## 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.

 ### Components
 
-- **Component 1**: [Description of what this component does]
-- **Component 2**: [Description of what this component does]
-- **Component 3**: [Description of what this component does]
+- 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.
+- Cache/Result Store (Redis): Available for caching or Celery result backend.
+- Infrastructure as Code (tofu/): OpenTofu modules provisioning cluster services (RabbitMQ, Redis, Argo CD, cert-manager, Cloudflare tunnel, etc.).
+- Deployment Chart (charts/myapp-chart/): Helm chart to deploy the application to Kubernetes.
 
 ### Technologies Used

+
+If needed, adjust compose services/ports in compose.yml.
+
+
 ## Deployment Instructions
 
-### Local Deployment
+### Local (Docker Compose)
 
+Described in the previous section (Manual Local Run)
+
+### Kubernetes (via OpenTofu + Helm)
+
+1) Provision platform services (RabbitMQ/Redis/ingress/tunnel/etc.) with OpenTofu
 ```bash
-# Step-by-step commands for local deployment
-# For example:
-# docker-compose up -d
-# kubectl apply -f manifests/
+cd tofu
+# copy and edit variables
+cp terraform.tfvars.example terraform.tfvars
+# authenticate to your cluster/cloud as needed, then:
+tofu init
+tofu plan
+tofu apply
 ```
 
-### Cloud Deployment
-
+2) Deploy the app using Helm
 ```bash
-# Commands for cloud deployment
-# Include any cloud-specific setup
+# Set the namespace
+kubectl create namespace myapp || true
+
+# Install/upgrade the chart with required values
+helm upgrade --install myapp charts/myapp-chart \
+  -n myapp \
+  -f charts/myapp-chart/values.yaml \
+  --set image.backend.repository=myorg/myapp-backend \
+  --set image.backend.tag=latest \
+  --set env.BACKEND_URL="https://myapp.example.com" \
+  --set env.FRONTEND_URL="https://myapp.example.com" \
+  --set env.SECRET="CHANGE_ME_SECRET"
+```
+Adjust values to your registry and domain. The chart’s NOTES.txt includes additional examples.
+
+3) Expose and access
+- If using Cloudflare Tunnel or an ingress, configure DNS accordingly (see tofu/modules/cloudflare and deployment/tunnel.yaml).
+- For quick testing without ingress:
+```bash
+kubectl -n myapp port-forward deploy/myapp-backend 8000:8000
+kubectl -n myapp port-forward deploy/myapp-frontend 5173:80
 ```
 
 ### Verification
 
 ```bash
-# Commands to verify deployment worked
-# How to check if services are running
-# Example health check endpoints
+# Check pods
+kubectl -n myapp get pods
+
+# Backend health
+curl -i http://127.0.0.1:8000/
+# OpenAPI
+open http://127.0.0.1:8000/docs
+
+# Frontend (if port-forwarded)
+open http://localhost:5173
