+## Download type - pie
+
+PIE (PHP Installer for Extensions) type sources refer to downloading PHP extensions from Packagist that follow the PIE standard.
+This method automatically fetches extension information from the Packagist repository and downloads the appropriate distribution file.
+
+The parameters included are:
+
+- `repo`: The Packagist vendor/package name, such as `vendor/package-name`
+
+Example (download a PHP extension from Packagist using PIE):
+
+```json
+{
+  "ext-example": {
+    "type": "pie",
+    "repo": "vendor/example-extension",
+    "path": "php-src/ext/example",
+    "license": {
+      "type": "file",
+      "path": "LICENSE"
+    }
+  }
+}
+```
+
+::: tip
+The PIE download type will automatically detect the extension information from Packagist metadata, 
+including the download URL, version, and distribution type. 
+The extension must be marked as `type: php-ext` or contain `php-ext` metadata in its Packagist package definition.
