 Zeby wystartowac aplikacje backendu najpierw nalezy postawic testowa baze danych na naszym komputerze za pomoca dockera. Jesli raz juz go odpalimy przy nastepnym razem bardzo mozliwe, ze wlaczy sie sam. AAby sprawdzic czy docker jesty wystartowany mozna uzyc `docker ps`
 
 ```
-docker-compose -f stack.yml up
-```
-
-Nastepnie w `restservice/src/main/resources/application.properties` nalezy podac ip naszego kontenera.
-
-```
-spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
-spring.datasource.url=jdbc:mysql://localhost:3306/test
-spring.datasource.username=root
-spring.datasource.password=example
-spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
-spring.jpa.hibernate.ddl-auto=create
-
-server.port=1285
+docker-compose -f stack.yml up -d
 ```
 
 Następnym krokiem jest odpalenie poniższych komend w terminalu.
+
 ```
 cd restservice
 mvn spring-boot:run
 ```
 
+## 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
+
+```
+python gettoken.py
+```
+
+Na koniec w przęglądarce dostaniesz w odpowiedzi token. W samym pliku można zmienić porty aplikacji jeśli to potrzebne.
+
+## Profiles
+
+W aplikacji posiadamy dwa profile. `dev` i `prod`. **Dev** używamy do testowania aplikacji lokalnie. **Pord** służy do stworzenia builda na produkcję.
+Profil wybieramy w pliku `restservice/src/main/resources/application.properties` wpisując odpowiednią nazwę
+
+```
+spring.profiles.active=prod
+```
+
+Jeżeli chcemy zmienić jakieś opcję dla pordukcji to robimy to w tym sammym katalogi w pliku `application-prod.properties` i dla dev analogicznie w `application-dev.properties`.
+W paczce dla proda w protpertiesach poufne dane odczytywane są ze zmiennych środowiskowych systemu na którym odpalana jest aplikacja. Ustawić trzeba następujące zmienne:
+
+-   PLANNAPLAN_MYSQL_DB_HOST - host bazy danych np `localhost`
+-   PLANNAPLAN_MYSQL_DB_PORT - port na którym działa baza
+-   PLANNAPLAN_MYSQL_DB - nazwa bazy dancyh. W profilu **dev** jest to np test
+-   PLANNAPLAN_MYSQL_DB_USERNAME - nazwa użytkownika bazy
+-   PLANNAPLAN_MYSQL_DB_PASSWORD - hasło użytkownika bazy
+
 ## Packaging
 
 Zeby spakowac apke do `jara` wystarcza dwie komendy zaczynajac z glownego katalogu projektu

 Utworzony zostanie jar w `restservice/target/restservice-1.0-SNAPSHOT.jar`. Oczywiscie zeby jar zadzialal kontenery dockerowe musza byc odpalone (lub baza danych na serwerze jesli zmienialismy propertisy z localhost)
 
+## Generowanie dokumentacji
+
+### Javadocs
+
+```bash
+mvn javadoc:javadoc
+```
+
+### Api docs
+
+Żeby zobaczyć dokumentację api trzeba wejść w przeglądarce na `http://localhost:1285/swagger-ui.html` po odpaleniu aplikacji.
+
+#### Nazewnictwo odpowiedzi
+
+Każdą odpowiedź zaczynamy od modelu, który opisuje np. `Courses` a kończymy na `Response`. Między tymi dwoma członami możemy dodawać modyfikatory opisujące dokładniej odpowiedź np. `Default`. W ten sposób możemy otrzymać nazwę `CoursesDefaultResponse.java`
+
 ## Troubleshooting
 
 Spring chyba cacheuje jakies dane dotyczace polaczenia wiec jesli spring wywali Ci blad `Connection Refused`, a wiesz, ze ta baza stoi na podanym ip i porcie to sprobuj
