+- [ ] Dont store data in database (security) - Load it on login (from CSAS API and local database), load automatically with email
+- [X] Go through the checklist
+- [X] Look for possible APIs (like stocks or financial details whatever)
+- [ ] Report - partly
+
+Summary of what has been accomplished since the last meeting in the following categories.
+
+### Coding
+Implemented CSAS API transactions fetch, Added tests with testing database on github actions, redone UI, 
+added currency exchange rate with CNB API
+
+### Documentation
+Not much - just updated the work done
+
+## Questions and Topics for Discussion (Before Meeting)
+
+1. Security regarding storing transactions - possibility of encryption
+2. Realisticaly what needs to be done for us to be done
+3. Question 3
+
+## Discussion Notes (During Meeting)
+The tracker should not store the transactions in the database - security vulnerability.
+
+## Action Items for Next Week (During Meeting)
+
+Last 3 minutes of the meeting, summarize action items.
+
+- [x] Change the name on frontend from 7project
+- [x] Finalize the funcionality and everyting in the code part
+- [ ] Try to finalize report with focus on reproducibility

+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

+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. 
 
-### Local (Docker Compose)
+1) Create 4 VMs with TalosOS

+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
 
-Described in the previous section (Manual Local Run)
+5) Apply the config to the VMs
+```bash
+#TODO: add config apply commands
+```

 ## 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
