 ### Install using OS package system
 
-PHP Mode is available from [package systems provided by several OSs](https://repology.org/project/emacs:php-mode/versions).  On Debian, and operating systems derived from it, such as Ubuntu, the easiest way to add PHP support to Emacs is `sudo apt install elpa-php-mode`.  "Stable" releases of these operating systems include a well-tested frozen version of this package that is always older than the latest upstream version of PHP Mode.  Autoloads and byte-compilation are automatic.
