+*** Django #1: Introduction
+**** Objective
+     - We will build a IPv6 ULA registry with Django in the
+       next lectures
+**** Lecture content
+     - Create a new directory in your learning cirle repository named "django"
+     - Write down the answers to the following questions in django/django.org
+     - Research and answer the following questions: (1/2 of the time)
+       - What is IPv6 ULA?
+	 - addresses that are only ment to be used in privte segment. 
+	 - unique Local address they can be easly identified by FD00::/8 
+	 - equivllent to privte address in v4  
+       - Which registries did exist historically?
+       - How should an IPv6 ULA registry work?
+     - Get started with Django
+       - Create a new python virtual env using `python3 -m venv`
+         - Create the venv in django/venv
+       - Create a file .gitignore in django/
+         - Add 'venv/' (without the quotes to that file
+         - Use magit to verify that the venv is being ignored
+         - Add and commit the .gitignore file
+       - Inside this virtual env, install django using `pip`
+       - Go to https://www.djangoproject.com/
+       - Finish tutorial 1: https://docs.djangoproject.com/en/3.0/intro/tutorial01/
+       - Commit the django code to your repository
+       - Exclude '*.pyc' in the .gitignore
+       - Also exclude the sqlite database
