+## Compatibility
+
+The Parse PHP SDK is continuously tested with the most recent releases of PHP to ensure compatibility. We follow the [PHP Long Term Support plan](https://www.php.net/supported-versions.php) and only test against versions that are officially supported and have not reached their end-of-life date.
+
+| Version | End-of-Life | Compatible |
+|---------|-------------|------------|
+| PHP 8.2 | Dec 2024    | ✅ Yes      |
+| PHP 8.1 | Nov 2023    | ✅ Yes      |
+
 ## Installation
 There are various ways to install and use this sdk. We'll elaborate on a couple here.
 Note that the Parse PHP SDK requires PHP 5.4 or newer. It can also run on HHVM (recommended 3.0 or newer).
