To start a Django app, you must first ensure that you have Django installed. If not, you can install it via pip: ```bash pip install Django ``` Once Django is installed, navigate to the directory where you want your new Django project and execute the following command in your terminal to create a new Django project: ```bash django-admin startproject projectname ``` Replace `'projectname'` with the name of your project. This will create a new directory with the project structure. Next, navigate into your new project directory: ```bash cd projectname ``` Now you can create a new Django app within your Django project with the following command: ```bash python manage.py startapp appname ``` Replace `'appname'` with what you want to name your application. This will create a directory 'appname' with a structure for an app. Remember, in Django, a project is a collection of configurations and apps. An app is a module within the project that does something. For example, a blog, a database of public records, etc. Don't forget to add your new app to INSTALLED_APPS in your settings.py file (located in projectname/projectname/settings.py) for Django to acknowledge it: ```python INSTALLED_APPS = [ #... 'appname', #... ] ``` Finally, run Django server: ```bash python manage.py runserver ``` Point your web browser to localhost:8000 and you should see your Django welcome page. Remember, Django follows the DRY principle: Don't Repeat Yourself, which promotes reusing the code. Please let me know if you encounter any issues during the process. Happy coding!
