 This extension is a debug adapter between VS Code and [XDebug](https://xdebug.org/) by Derick Rethan. XDebug is a PHP extension (a `.so` file on Linux and a `.dll` on Windows) that needs to be installed on your server.
 
-1.  [Install XDebug](https://xdebug.org/docs/install)
-    **_I highly recommend you make a simple `test.php` file, put a `phpinfo();` statement in there, then copy the output and paste it into the [XDebug installation wizard](https://xdebug.org/wizard.php). It will analyze it and give you tailored installation instructions for your environment._** In short:
-    - On Windows: [Download](https://xdebug.org/download.php) the appropiate precompiled DLL for your PHP version, architecture (64/32 Bit), thread safety (TS/NTS) and Visual Studio compiler version and place it in your PHP extension folder.
-    - On Linux: Either download the source code as a tarball or [clone it with git](https://xdebug.org/docs/install#source), then [compile it](https://xdebug.org/docs/install#compile).
-2.  [Configure PHP to use XDebug](https://xdebug.org/docs/install#configure-php) by adding `zend_extension=path/to/xdebug` to your php.ini. The path of your php.ini is shown in your `phpinfo()` output under "Loaded Configuration File".
-3.  Enable remote debugging in your php.ini:
-
-```ini
-[XDebug]
-xdebug.remote_enable = 1
-xdebug.remote_autostart = 1
-```

+
+   There are other ways to tell XDebug to connect to a remote debugger than `remote_autostart`, like cookies, query parameters or browser extensions. I recommend `remote_autostart` because it "just works". There are also a variety of other options, like the port (by default 9000), please see the [XDebug documentation on remote debugging](https://xdebug.org/docs/remote#starting) for more information.
