Django version 3.0.8, using settings 'my_projects.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CTRL-BREAK.

python manage.py runserver is a command in Django that starts the development server. When you run this command, Django will start a lightweight web server on your local machine, allowing you to view your Django project in a web browser.

The command python manage.py is used to interact with your Django project through the command line. runserver is a specific command that tells Django to start the development server.

Go to: http://127.0.0.1:8000/, you will see small rocket and message: The install worked successfully! Congratulations!

Go to: http://127.0.0.1:8000/admin/ to access Admin Panel, but you can't login because we didn't created admin credentials - yet.

Cancel server with Ctrl + Break, we need to create superuser - admin.

A superuser is a user account with all permissions to manage and modify the application. Superusers can access the admin site, which provides a graphical interface for managing the database and application settings.

We need to create a superuser during the initial setup of a Django application, so that we can have access to the admin site and perform administrative tasks such as creating and managing database objects, managing user accounts, etc. The superuser account also serves as a security measure, allowing only authorized users to perform such tasks.

But first - let's handle migrations:

C:\my_projects>python manage.py migrate
