 </ul>
 
 For more details, consult the [constants file](https://github.com/nicoverbruggen/phpmon/blob/main/phpmon/Common/Core/Constants.swift#L16) file to see which versions are supported.
 
+Backports are available via [this tap](https://github.com/shivammathur/homebrew-php). For more information about those backports, please see the next FAQ entry.
+
+For maximum compatibility with older PHP versions, you may wish to keep using Valet 2 or 3.

+<details>
+<summary><strong>How do I install additional versions of PHP, including legacy versions?</strong></summary>
+
+Assuming you have installed the `php` formula, the latest stable version of PHP is installed. At the time of writing, this is PHP 8.2.
+
+You can install other supported versions of PHP out of the box, so `php@8.0` and `php@8.1` at the time of writing.
+
+If you wish to install older (officially unsupported) versions of PHP for local use, you can do so by using [Shivam Mathur's tap](https://github.com/shivammathur/homebrew-php):
+
+```sh
+brew tap shivammathur/php
+```
+
+You may find that this tap is already in use: if you've used Valet before, it automatically uses this tap for legacy versions of PHP.
+
+You can then install those older versions:
+
+```sh
+brew install php@7.0
+brew install php@7.1
+...
+```
+
+**Always make sure to restart PHP Monitor after installing or upgrading PHP versions!**
+
+> *Note*: Using this tap may cause [temporary alias conflicts](https://github.com/nicoverbruggen/phpmon/issues/54#issuecomment-979789724) while the core tap alias and the tap's alias refer to a different version of PHP, but this is generally speaking a minor inconvenience, since this normally only applies when a new PHP version releases.

-     
-     - Parameter constraint: The full constraint as a string (e.g. "^7.0")
-     - Parameter strict: Whether the patch version check is strict. See more below.
-     
-     The strict mode does not matter if a patch version is provided for all versions in the collection.
-     
-     Strict mode assumes that any PHP version lacking precise patch information, e.g. inferred
-     from Homebrew corresponds to the .0 patch version of that version. The default, which is imprecise,
-     assumes that the patch version is .999, which means that in all cases the patch version check is

-     **STRICT MODE (= patch precision on)**
-     
-     Given versions 8.0.? and 8.1.?, but the requirement is ^8.0.1, in strict mode only 8.1.? will
-     be considered valid (8.0 translates to 8.0.0 and as such is older than 8.0.1, 8.1.0 is OK).
-     When checking against actual PHP versions installed by the user (with patch precision), use
-     strict mode.
-     
-     **NON-STRICT MODE (= patch precision off)**
-     
-     Given versions 8.0.? and 8.1.?, but the requirement is ^8.0.1, in non-strict mode version 8.0
-     is assumed to be equal to version 8.0.999, which is actually fine if 8.0.1 is the required version.
-     In non-strict mode, the patch version is ignored for regular version checks (no caret / tilde).
-     If checking compatibility with general Homebrew versions of PHP, do NOT use strict mode, since
-     the patch version there is not used. (The formula php@8.0 suffices for ^8.0.1.)
