+# Token obtaining
 
 Żeby tesotwać API wpełni potrzebny nam jest token który otrzymujemy na podstawie ticketa z systemu autoryzacyjnego **CAS**. Z tego powodu system autoryzacji działa inaczej niż w "książkowych" restowych aplikacjach i np Postman za nas jej nie dokona. Musimy mu podać już uzyskany token. Aby łatwo go uzyskać odpal skrypt
 
-```
+```bash
 python gettoken.py
 ```
 
+Jeżeli chcesz używać skryptu zmiejaniąc gdzie znajduje się backend wpisz:
+
+```bash

+```
+
+Jeżeli chcesz używać skryptu bez uruchamiania przeglądarki wpisz:
+
+```bash
+python gettoken.py no-browser
+```

 Na koniec w przęglądarce dostaniesz w odpowiedzi token. W samym pliku można zmienić porty aplikacji jeśli to potrzebne.
