+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
+- 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
+- There is also a Task planner, that executes periodic tasks, like fetching new transactions automatically from the Bank API
+
 ### 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.

 ## Deployment Instructions
+### Setup Cluster
+Deployment should work on any Kubernetes cluster. However, we are using 4 TalosOS virtual machines (1 control plane, 3 workers) 
+running on top of Proxmox VE. 
 
+1) Create 4 VMs with TalosOS
+2) Install talosctl for your OS: https://docs.siderolabs.com/talos/v1.10/getting-started/talosctl
+3) Generate Talos config
+```bash
+# TODO: add commands
+```
+4) Edit the generated worker.yaml
+- add google container registry mirror
+- add modules from config generator 
+- add extramounts for persistent storage
+- add kernel modules
+
+5) Apply the config to the VMs
+```bash
+#TODO: add config apply commands
+```
+
+6) Verify the cluster is up
+```bash
+```
+
+7) Export kubeconfig
+```bash
+# TODO: add export command
+```

 ## Testing Instructions
+The tests are located in 7project/backend/tests directory
+If you want to test locally, you have to have the DB running locally as well (start the docker compose in /backend).
+```bash
+cd backend
+```
 
 ### Unit Tests
-
+There are only 3 basic unit tests, since our services logic is very simple
 ```bash
-# Commands to run unit tests
-# For example:
-# go test ./...
-# npm test
+pytest tests/test_unit_user_service.py
 ```
 
 ### Integration Tests
-
+There are 11 basic unit tests, testing the individual backend API logic
 ```bash
-# Commands to run integration tests
-# Any setup required for integration tests
+pytest tests/test_integration_app.py 
 ```
 
 ### End-to-End Tests
-
+There are 7 e2e tests testing more complex app logic
 ```bash
-# Commands to run e2e tests
-# How to set up test environment
+pytest tests/test_e2e.py
 ```
