 ## Why DDEV Xdebug "Just Works"
 
-One of DDEV's proudest achievements is that Xdebug typically works without any configuration. This seems simple, but it's solving a complex problem: PHP running inside a Docker container needs to connect back to your IDE on your host machine, and the container has no inherent knowledge of how to reach the host.
+One of our proudest achievements with DDEV is that Xdebug typically works without any configuration. This seems simple, but it's solving a complex problem: PHP running inside a Docker container needs to connect back to your IDE on your host machine, and the container has no inherent knowledge of how to reach the host.
 
 The solution is `host.docker.internal` - a special hostname that resolves to the host machine's IP address from the container's perspective. The challenge is that this works differently across platforms:
 
-- **macOS and Windows (Docker Desktop)**: Automatically provides `host.docker.internal`
-- **Linux**: No built-in `host.docker.internal` support
+- **macOS and Windows**: Some Docker providers like Docker Desktop and Colima automatically provide `host.docker.internal`
+- **Linux**: No direct built-in `host.docker.internal` support
 - **WSL2**: Complex networking scenarios depending on NAT vs. mirrored mode
 
 DDEV automatically detects your environment and configures `host.docker.internal` correctly:
 
-- On Linux, DDEV adds the host gateway IP to `/etc/hosts` in the container
+- On Linux, DDEV use the host gateway feature of docker-compose
 - On WSL2, DDEV determines whether to use the Windows host IP or the WSL2 IP based on your configuration
-- On all platforms, DDEV validates the IP and reconfigures if needed
 
 This means when you run `ddev xdebug on`, the extension is already configured to connect to `host.docker.internal:9003`, and that hostname reliably resolves to wherever your IDE is listening.

 The most common debugging issue is setting a breakpoint in code that never runs. You might set a breakpoint in a function that's not called, a conditional branch that's not taken, or a file that's not included.
 
-**Solution**: Start with a breakpoint in the main entry point, usually `index.php` or `web/index.php`. This ensures your breakpoint will definitely be hit. Once you confirm Xdebug is working, you can move your breakpoint to the specific code you want to debug.
