 ## Installation
 
-To build and install the driver:
+### With pie
 
- $ pecl install mongodb
- $ echo "extension=mongodb.so" >> `php --ini | grep "Loaded Configuration" | sed -e "s|.*:\s*||"`
+To install this extension, you need [pie](https://github.com/php/pie) installed on your system. `pie` is a modern tool for managing PHP extensions.
+
+Install the [`mongodb/mongodb-extension`](https://packagist.org/packages/mongodb/mongodb-extension) package from Packagist using the following command:
+
+```shell
+pie install mongodb/mongodb-extension
+```
+
+This will automatically download, build, and enable the MongoDB extension for your PHP installation.
+
+Add a version constraint after the extension name to restrict can be installed:
+
+```shell
+pie install mongodb/mongodb-extension:^2.1.0
+```
+
+The constraint `^2.1.0` will install the latest version `>= 2.1.0 < 3.0.0-dev`.
+
+
+For more details on using `pie`, see the [pie documentation](https://github.com/php/pie).
