1. install docker
2. copy transactions_2_million.csv to src/ManagedCodeTestTask.Api/. Git does not support 100+MB files
3. run docker-compose build to build project.
4. run docker-compose --env-file .env -f .\docker-compose.override.yml -f .\docker-compose.yml up -d to run the db and app
5. visit http://localhost:4847/swagger/index.html
6. call POST: /api/transactions with body:{"filePath": "transactions_2_million.csv"}
7. be patient
8. call GET: /api/transactions

for file results - put true in the parameter. Open managedcodetesttask_output_files volume to find and download output_file.json with JSON results

Personal notes: JSON file report generation should be a separate controller, not a flag. I had a crazy weekend so I had to make some shortcuts.
