 For example, behaviors can:
 
+* Move the camera to follow an object.
 * Automatically remove objects from a scene when they move outside the edges of the screen.
+* Handle health, damage, ammo and other elemnts of the player or an enemy.
 * Make objects move in a realistic way by following the laws of physics.
 * Allow players to move an object with the arrow keys.

-## List of behaviors
+## Most commonly used behaviors
 
-This section lists the different types of behaviors, each of which is useful for adding different types of features to objects.
+Here are some commonly used behaviors:
 
 - [Anchor](/gdevelop5/behaviors/anchor)
-- [Bounce](/gdevelop5/behaviors/bounce)
 - [Destroy outside screen](/gdevelop5/behaviors/destroyoutside)
 - [Draggable](/gdevelop5/behaviors/draggable)
 - [Pathfinding](/gdevelop5/behaviors/pathfinding)

 - [Top-down movement](/gdevelop5/behaviors/topdown)
 - [Tween](/gdevelop5/behaviors/tween)

+Refer to the linked pages to learn more about each behavior. While these behaviors are often used, the [full list of behaviors available in GDevelop](/gdevelop5/extensions/) keeps growing everyday: see the [list of all GDevelop extensions](/gdevelop5/extensions/) to discover them.
 
-### Deprecated behaviors
+Behaviors can be contributed by the community or the GDevelop core development team. You can [create new behaviors](/gdevelop5/behaviors/events-based-behaviors), with or without code, directly inside GDevelop.

+!!! tip
+
+    When your game is growing, it's a good idea to make [your own behaviors]((/gdevelop5/behaviors/events-based-behaviors)) for each object in your game. Making your own behaviors allows you to keep your game modular.
 
 ## Adding a behavior to an object
 
-1. Right-click an object in the **Objects** panel.
-2. Select **Edit behaviors**.
-3. Click the **Add a behavior to the object** button.
-4. Select a behavior from the list.
-5. Customize the behavior. The available settings depend on the behavior.
-6. Click **Apply**.
+To add a behavior to an object you can either:
 
-![](/gdevelop5/behaviors-demo-create.gif)
+* Select the object in the list of objects and then, in the **Properties** panel, click on the + next to the "Behaviors" section:
 
-## Installing new behaviors

-Anyone can [create custom behaviors](/gdevelop5/behaviors/events-based-behaviors) and share them with the GDevelop community.
+  You can then browse the list of behaviors. The most commonly used are displayed at the top of the list:
