+```
+
+Create a new local Git repository:
+
+```shell
+$ cd materials/django-hosting-heroku
+$ git init
+$ git add .
+$ git commit -m "Initial commit"
+```
+
+Deploy the code to Heroku:
+
+```shell
+$ heroku login
+$ heroku create
+$ heroku config:set DEBUG=True SECRET_KEY=$(date | base64)
+$ git push heroku master
+$ heroku open
+```
