+## Analiza dyskusji na forum (Development)
+
+### Wymagania:
+
+- Python 
+- Django >= 3.0.5
+
+### Środowisko wirtualne
+Zaczynamy od stworzenia i uruchomienia środowiska wirtualnego, przy pomocy poleceń:
+```bash
+$ python3 -m venv myvenv
+$ source myvenv/bin/activate
+```
+Powinniśmy ujrzeć (myvenv) poprzedzające nasza nazwę użytkownika w wierszu poleceń.
+
+### Instalacja Django
+Pierwszym krokiem będzie zaktualizowanie menedżera pakietów języka Python:
+```bash
+$ python3 -m pip install --upgrade pip
+```
+Instalujemy pakietu Django przy pomocy listy wymagań:
+```bash
+pip install -r requirements.txt
+```
+
+### Uruchomienie
+
+Aby uruchomić wersję prototyp aplikacji, w pierwszej kolejności należy zainicjalizować bazę danych:
+```bash
+$ python manage.py migrate --run-syncdb
+```
+Następnie uruchamiamy serwer WWW:
+```bash
+$ python manage.py runserver
+```
+Aplikacja dostępna jest pod adresem `127.0.0.1:8000`
+Aby zakończyć działanie serwera, korzystamy w kombinacji klawiszy CTRL + C w terminalu, w którym uruchomiliśmy usługę.
+
+Aby opuścić środowisko wirtualne, korzytamy z polecenia `deactivate`.
