  </h3>
  <p>
   Let's start by creating a new Django project:
  </p>
  <pre>
<code>
django-admin startproject myproject
</code>
</pre>
  <p>
   This command will create a directory named "myproject" containing the core project files: `manage.py`, `myproject/`, and `myproject/settings.py`.  You can now navigate into the project directory using:
  </p>
  <pre>
<code>
cd myproject
</code>
</pre>
  <h3>
   Creating a Django App
  </h3>
  <p>
   Now, let's create a Django app called "blog" within your project:
  </p>
  <pre>
<code>
python manage.py startapp blog
</code>
</pre>
  <p>
   This creates a "blog" directory containing the following files:
  </p>
  <ul>
   <li>
    <b>
     models.py:
    </b>
    Where you define your database models.
   </li>
   <li>
    <b>
     views.py:
    </b>
    Where you write your view functions to handle requests and generate responses.
   </li>
   <li>
    <b>
     urls.py:
    </b>
    The URL configuration for your app.
   </li>
   <li>
    <b>
     templates/blog:
    </b>
    A directory for your HTML templates.
   </li>
   <li>
    <b>
     tests.py:
    </b>
    For writing unit tests for your app.
   </li>
   <li>
    <b>
     __init__.py:
    </b>
    An empty file that indicates this directory is a Python package.
   </li>
  </ul>
  <h3>
   Configuring Your App in settings.py
  </h3>
  <p>
   Open the `myproject/settings.py` file and add your new app to the `INSTALLED_APPS` list:
  </p>
  <pre>
<code>
INSTALLED_APPS = [
    # ... other apps
    'blog',
]
</code>
</pre>
  <h3>
   Adding URL Patterns to urls.py
  </h3>
  <p>
   Open the `myproject/urls.py` file and include your app's URLs using the `include` function:
  </p>
  <pre>
<code>
from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('blog.urls')),
]
</code>
</pre>
  <p>
   Now, create the `blog/urls.py` file and define patterns for your views:
  </p>
  <pre>
<code>
from django.urls import path
from . import views

urlpatterns = [
    path('', views.index, name='index'),
]
</code>
</pre>
  <h3>
   Creating a View Function
  </h3>
  <p>
   In your `blog/views.py` file, create a simple view function:
  </p>
  <pre>
<code>
from django.shortcuts import render

def index(request):
    return render(request, 'blog/index.html', {})
</code>
</pre>
  <h3>
   Creating a Template
  </h3>
  <p>
   Create the `blog/templates/blog/index.html` template:
  </p>
  <pre>
<code>
<!DOCTYPE html>

<html>
<head>
    <title>My Blog</title>
</head>
<body>
    <h1>Welcome to My Blog!</h1>
</body>
</html>
</code>
</pre>
  <h3>
   Running Your Development Server
  </h3>
  <p>
   Finally, run your development server:
  </p>
  <pre>
<code>
python manage.py runserver
</code>
</pre>
  <p>
   This will start a development server at `http://127.0.0.1:8000/`. Access the server in your browser and you should see "Welcome to My Blog!"
  </p>
