 Note: replace `dev-main` with a [version constraint](https://getcomposer.org/doc/articles/versions.md#writing-version-constraints), e.g. `^4.3` - see [releases](https://github.com/chillerlan/php-qrcode/releases) for valid versions.
-For PHP version ...
-  - 7.4+ use `^4.3`
-  - 7.2+ use `^3.4.1` (v3.4.1 also supports PHP8)
-  - 7.0+ use `^2.0`
-  - 5.6+ use `^1.0` (please let PHP 5 die!)
-
-In case you want to keep using `dev-main`, specify the hash of a commit to avoid running into unforseen issues like so: `dev-main#cb69751c3bc090a7fdd2f2601bbe10f28d225f10`
-
-PSA: [PHP 7.0 - 7.3 are EOL](https://www.php.net/supported-versions.php) and therefore the respective `QRCode` versions are also no longer supported!
