 Handlers are Python functions that respond to WebSocket messages from the client. They contain your business logic and can render HTML, update the database, broadcast to multiple users, and more.
 
-** Creating Handlers
+** Your First Handler
 
-Use the ~@liveview_handler~ decorator to register functions that can be called from the client:
+Let's start with the simplest possible handler. This handler will be called when a button is clicked and will update a section of the page.
+
+Python code:
 
 #+BEGIN_SRC python
 from liveview import liveview_handler, send
-from django.template.loader import render_to_string
 
 @liveview_handler("say_hello")
 def say_hello(consumer, content):
-    """
-    Args:
-        consumer: WebSocket consumer instance
-        content: dict with:
-            - function: str - the function name
-            - data: dict - custom data from data-data-* attributes
-            - form: dict - form input values
-            - lang: str - current language
-            - room: str - room identifier
-    """
-    name = content.get("form", {}).get("name", "World")
-
-    html = render_to_string("hello_message.html", {
-        "message": f"Hello, {name}!"
+    send(consumer, {
+        "target": "#greeting",
+        "html": "<p>Hello, World!</p>"
     })
+#+END_SRC
+
+HTML code:
+
+#+BEGIN_SRC html
+<div>
+    <div id="greeting"></div>
+    <button
+        data-liveview-function="say_hello"
+        data-action="click->page#run">
+        Say Hello
+    </button>
+</div>
+#+END_SRC
+
+When you click the button:
+1. The frontend sends a WebSocket message with ~function: "say_hello"~
+2. Django LiveView calls the ~say_hello~ handler
+3. The handler sends back HTML to replace the content of ~#greeting~
+4. The page updates instantly without a full reload
+
+** Working with Form Data
+
+Most handlers need to receive data from the user. All form inputs within the same container are automatically sent to your handler.
+
+Python code:
+
+#+BEGIN_SRC python
+@liveview_handler("greet_user")
+def greet_user(consumer, content):
+    # Get the name from form data
+    name = content["form"].get("name", "Anonymous")
 
     send(consumer, {
         "target": "#greeting",
+        "html": f"<p>Hello, {name}! Welcome to Django LiveView.</p>"
+    })
+#+END_SRC
+
+HTML code:
+
+#+BEGIN_SRC html
+<div>
+    <div id="greeting"></div>
+    <input type="text" name="name" placeholder="Enter your name">
+    <button
+        data-liveview-function="greet_user"
+        data-action="click->page#run">
+        Greet Me
+    </button>
+</div>
+#+END_SRC
+
+The ~content["form"]~ dictionary contains all input values with their ~name~ attribute as the key.
+
+** Using Templates for Complex HTML
+
+For anything beyond simple strings, use Django templates to render your HTML.
+
+Python code:
+
+#+BEGIN_SRC python
+from django.template.loader import render_to_string
+
+@liveview_handler("show_profile")
+def show_profile(consumer, content):
+    user_id = content["form"].get("user_id")
+
+    # Get user from database
+    from .models import User
+    user = User.objects.get(id=user_id)
+
+    # Render template with context
+    html = render_to_string("profile_card.html", {
+        "user": user,
+        "is_online": True
+    })
+
+    send(consumer, {
+        "target": "#profile-container",
         "html": html
     })
 #+END_SRC
 
+HTML code:
+
+#+BEGIN_SRC html
+<div>
+    <div id="profile-container"></div>
+    <input type="hidden" name="user_id" value="123">
+    <button
+        data-liveview-function="show_profile"
+        data-action="click->page#run">
+        Load Profile
+    </button>
+</div>
+#+END_SRC
+
+Template (~profile_card.html~):
+
+#+BEGIN_SRC html
+<div class="profile-card">
+    <img src="{{ user.avatar }}" alt="{{ user.name }}">
+    <h3>{{ user.name }}</h3>
+    <p>{{ user.bio }}</p>
+    {% if is_online %}
+        <span class="badge">Online</span>
+    {% endif %}
+</div>
+#+END_SRC
+
+** Understanding the Content Parameter
+
+Every handler receives two parameters: ~consumer~ and ~content~. The ~content~ dictionary contains all the information from the client.
+
+#+BEGIN_SRC python
+@liveview_handler("example")
+def example(consumer, content):
+    # content structure:
+    # {
+    #     "function": "example",           # Handler name
+    #     "form": {...},                   # All form inputs
+    #     "data": {...},                   # Custom data-data-* attributes
+    #     "lang": "en",                    # Current language
+    #     "room": "user_123"              # WebSocket room identifier
+    # }
+    pass
+#+END_SRC

-** Using the send() function
+** Using Custom Data Attributes
 
-The ~send()~ function sends data back to the client with many options:
+Sometimes you need to send additional data that isn't part of a form. Use ~data-data-*~ attributes for this.
 
-*** Replace HTML (Basic Update)
+Python code:
 
 #+BEGIN_SRC python
-@liveview_handler("update_content")
-def update_content(consumer, content):
+@liveview_handler("delete_comment")
+def delete_comment(consumer, content):
+    # Access custom data from data-data-* attributes

+        "remove": True  # Remove the element from DOM
     })
 #+END_SRC
 
-*** Append HTML
+HTML code:

+#+BEGIN_SRC html
+<div id="comment-123" class="comment">
+    <p>This is a comment</p>
+    <button
+        data-liveview-function="delete_comment"

+#+END_SRC
+
+The attribute ~data-data-comment-id~ becomes ~comment_id~ (with underscores, not camelCase) within ~content["data"]~.
+
+** Appending Content to Lists
+
+When building dynamic lists (like infinite scroll or chat messages), you want to add items without replacing the entire list.
+
+Python code:
 
 #+BEGIN_SRC python
-@liveview_handler("add_item")
-def add_item(consumer, content):
+@liveview_handler("load_more_posts")
+def load_more_posts(consumer, content):
+    page = int(content["form"].get("page", 1))
+
+    # Get next page of posts
+    from .models import Post
+    posts = Post.objects.all()[(page-1)*10:page*10]
+
+    # Render new posts
+    html = render_to_string("posts_list.html", {
+        "posts": posts
+    })
+
     send(consumer, {
-        "target": "#items-list",
-        "html": "<li>New item</li>",
-        "append": True  # Adds to the end
+        "target": "#posts-container",
+        "html": html,
+        "append": True  # Add to the end instead of replacing
     })
 #+END_SRC
 
-*** Remove Element
+HTML code:
+
+#+BEGIN_SRC html
+<div id="posts-container">
+    <!-- Existing posts here -->
+</div>
+
+<input type="hidden" name="page" value="2">
+<button
+    data-liveview-function="load_more_posts"
+    data-action="click->page#run">
+    Load More
+</button>
+#+END_SRC
+

+    <p>{{ post.content }}</p>
+</article>
+{% endfor %}
+#+END_SRC
+
+** Removing Elements from the DOM
+
+Instead of hiding elements with CSS, you can completely remove them from the page.
+
+Python code:
 
 #+BEGIN_SRC python
-@liveview_handler("delete_item")
-def delete_item(consumer, content):
-    item_id = content["data"]["id"]
-    # Delete from database...

+    notification_id = content["data"]["notification_id"]
 
+    # Archive in database
+    from .models import Notification
+    Notification.objects.filter(id=notification_id).update(archived=True)
+
+    # Remove from page
     send(consumer, {
-        "target": f"#item-{item_id}",

+    <p>You have a new message</p>
+    <button
+        data-liveview-function="archive_notification"
+        data-data-notification-id="42"
+        data-action="click->page#run">
+        Dismiss
+    </button>
+</div>
+#+END_SRC
+
+** Updating the URL Without Page Reload
+
+Create SPA-like navigation by updating both content and the browser URL.
+
+Python code:
 
 #+BEGIN_SRC python
-@liveview_handler("navigate")
-def navigate(consumer, content):
+@liveview_handler("navigate_to_profile")
+def navigate_to_profile(consumer, content):
+    user_id = content["data"]["user_id"]
+
+    # Get user data
+    from .models import User
+    user = User.objects.get(id=user_id)
+
+    # Render profile page
+    html = render_to_string("profile_page.html", {
+        "user": user
+    })
+
     send(consumer, {
-        "target": "#content",
-        "html": render_to_string("new_page.html"),
-        "url": "/new-page/",
-        "title": "New Page Title"
+        "target": "#main-content",
+        "html": html,
+        "url": f"/profile/{user.username}/",  # Update browser URL
+        "title": f"{user.name} - Profile"     # Update page title
     })

-*** Scroll Management
+HTML code:
+
+#+BEGIN_SRC html
+<div id="main-content">
+    <h1>Home Page</h1>
+    <button
+        data-liveview-function="navigate_to_profile"

+        data-action="click->page#run">
+        View Profile
+    </button>
+</div>
+#+END_SRC
+
+The browser's back/forward buttons will work correctly, and users can bookmark or share the URL.
+
+** Scrolling to Elements
+
+After updating content, you often want to scroll to a specific element or to the top of the page.
+
+Python code:
 
 #+BEGIN_SRC python
-@liveview_handler("show_section")
-def show_section(consumer, content):
-    send(consumer, {
