+### Folder Hierarchy
+
+Your project's root folder (the outer most) contains the following
+
+- `Pipfile`, `Pipfile.lock` - to track your installed packages as mentioned previously
+- `.gitignore` - to exempt some files from being tracked in your version control (Git)
+
+#### Project Folder
+

+
+The folder immediately proceeding your first one contains your Django project, created by the command `django-admin startproject PROJECT\_NAME` which you previously executed
+
+This contains the following
+
+- `manage.py` - The entry point to your Django app (e.g. the `python manage.py runserver` command and such)
+- `db.sqlite3` - The default database file for Django, which uses [SQLite](https://www.sqlite.org/) (you can switch to PostgreSQL or MySQL later on)
+- Another folder which contains your project's main config or app
+
+#### Django Apps  
+
+
+Django divides your projects into groups called apps. When you start a new project, you start off with your first app.
+
+In this case, my first app is named `djangobackend`

+
+That seems a bit confusing doesn't it?
+
+#### Renaming the Config App
+
+To make things clearer, you can opt to rename the main app of your Django project. These are the changes you must make
+
+- Rename the main app folder to `config`

+
+- Open `asgi.py` and change line 14 to point to **config.settings** instead of **PROJECT_NAME.settings**

+
+- Do the same for the `wsgi.py` file, also in line 14

+
+- Go to `settings.py` and set **ROOT_URLCONF** in line 52 to **config.urls** instead of **PROJECT_NAME.urls**

+- Do the same for **WSGI_APPLICATION** in `settings.py`, line 70

+
+- In `manage.py`, change line 19 to point to **config.settings** instead of **PROJECT_NAME.settings**

+
+With that, you should be good to go. Double check your setup by starting the Django app once again

+If you followed everything correctly, you should see the same page as before

+
+### Setting up DRF
+
+Your current setup only includes Django. To proceed with Django REST Framework, we will need to add it to our project.
+
+You've already installed Django REST Framework in the previous steps (e.g. `pipenv install django djangorestframework`).
+
+To register it as an app in our project. Open your `settings.py` file and look for the **INSTALLED_APPS** section
+
+![5bc2f2801c226ade60ad52496486ff78_MD5](_resources/3%20-%20Project%20Structure/5bc2f2801c226ade60ad52496486ff78_MD5.jpg)
+
+Add **rest_framework** to **INSTALLED_APPS**

+The next section will then tackle building a REST API with DRF
