+------------------
+
+**Add a new form**
+
+- We will now add a login form to the ```forms.py``` file located in ```blog``` folder
+- Add the following code to the file;
+
+      from django.contrib.auth.forms import AuthenticationForm 
+      from django import forms
+
+      # If you don't do this you cannot use Bootstrap CSS

+Slide 8:
+--------------------
+
+**Add the form to the URL configuration**
+
+- We will now add the form that we just created to the URL configuration of ```/login``` URL
+
+      # myproject/urls.py
+
+      from django.conf.urls import include, url
+      from django.contrib import admin

+          url(r'^login/$', auth_views.login, {'template_name': 'login.html', 'authentication_form': LoginForm}}), # Add this variable 'authentication_form'
+      ]
+
+Slide 8:
+--------------------
+
+**Modifying the views**
+
+- You will have to add this line ```@login_required(login_url="login/")``` above all the function in the ```views.py```
+- This is called a decorator.
+- It is a special function and a built-in feature in django that allows you to verify if the current session of the User is authenticated.
+- In case the user is not logged in / authenticated, the user is redirected to the link specified in the variable ```login_url```
+
+Example:
+
+      # blog/views.py
+
+      @login_required(login_url="login/")
+      def get_blogs(request, username):
+          ...
+
+      @login_required(login_url="login/")
+      def edit_blogs(request, blog_id):
+          ...
+
+      @login_required(login_url="login/")
+      def edit_articles(request, article_id):
+        ` ...
