-`db/main.py` is an *extremely* badly-written script that reads files (`pytania.csv` and `punkty.csv`) published by the Ministry of Infrastructure and imports them into a database
-- `db/pytania.csv` is the `katalog_pytania_egzminacyjne_kandydat__14112024.xlsx` file from [here](https://www.gov.pl/web/infrastruktura/prawo-jazdy), opened in Libreoffice Calc and saved as csv
-- `db/punkty.csv` isn't published by the Ministry, so you have to send a freedom of information request to acquire it; it is processed the same way as `pytania.csv`

+`main.py` is an _extremely_ badly-written script that reads files (`pytania.csv` and `punkty.csv`) shared by the Ministry of Infrastructure and imports them into a postgresql database

+- `db/pytania.csv` is the `katalog_pytania_egzminacyjne_kandydat__14112024.xlsx` file from [here](https://www.gov.pl/web/infrastruktura/prawo-jazdy)
+- `db/punkty.csv` isn't published by the Ministry, so you have to send a public information request to acquire it - we have received an XLSX
+  both of them are converted to CSV

+# Requirements

+- postgres server
+- python3
+- packages from requirements.txt (`pip install -r requirements.txt`)
+- files above (either already CSV'd from this repo or converted by yourself from official, most probably fresher sources)

-The basic tasks can be queried like so:
+## Criteria
+
+Categories are as such:
+
+- A
+- B
+- C
+- D
+- T
+- AM
+- A1
+- A2
+- B1
+- C1
+- D1
+- PT
+
+Languages as such:

+- PL
+- EN
+- UA
+- DE
+
+# Basic tasks query
+
+According to the Ministry of Infrastructure, in an exam there are (basic):
+
+- 4 questions for 1 point
+- 6 questions for 2 points
+- 10 questions for 3 points
+  so NO_OF_QUESTIONS and WEIGHT_OF_QUESTIONS should be set accordingly to the requirements above (and of course set category & lang to your liking)
+
 ```sql
-SELECT tasks.correct_answer, tasks.media_url, tasks.weight, questions.text
