+Hello there! Thank you for considering a pull request for PHP Monitor. 
+
+Please read the text below first before you submit your PR.
+
+## Do not PR unless...
+
+In order to make development and maintenance of PHP Monitor easier, I ask that you _avoid_ making a pull request in the following situations:
+
+* No issue has been associated with the changes you‘d like to merge
+* You have not announced you will be addressing a particular issue
+* The PR is a low effort change: e.g. commits that only fix typos or phrasing may not be accepted
+
+(If you believe the phrasing of particular text in the app is unclear or incorrect, please open an issue first.)
+
+In short: It is usually best to *get in touch first* if you are making substantial changes.
+
+## About destination branches
+
+Please keep in mind that `main` is reserved for the current code state of the latest release and should *never* be the destination branch unless a new release is happening. **Merge requests that target `main` will be closed without mercy.**
+
+Usually, the best target is the stable `dev/x.x` branch that corresponds with the latest major version that is released. 
+
+There may be a newer branch available, which is an appropriate place for bigger changes, but please keep in mind that it is usually best to announce you‘ll be working on such a change before you spend the time, since as the lead contributor I might not even want said change in the app. Thank you.
+
+## Your changes
+
+(feel free to remove the disclaimer above)
+
+* Affected parts of the app: shared code / UI code / CLI (remove what does not apply)
+* Estimated impact on performance: none / low / high (remove what does not apply)
+* Made a new build with Xcode and tested this: yes / no (remove what does not apply)
+* Tested on macOS version + architecture: (e.g. "Monterey on M1" or "Big Sur on Intel")
+* References issue(s): (please reference the issue here, using # and the number of the issue)
+
+(please describe what you have changed here)

+<summary><strong>How do I get various applications to show up in the domain list's right-click menu?</strong></summary>
 
-This is a security feature of Brew. When you start a service as an administrator, the root user becomes the owner of relevant binaries. 
+When you select and right-click on a domain, you can open these directories with various applications. This can help speed up your workflow. However, for these apps to show up, they must be detected first.
 
-You will need to manually clean up those folders yourself using `rm -rf` (or by manually removing those folders via Finder).
+The supported apps are: <i>PhpStorm, Visual Studio Code, Sublime Text, Sublime Merge, iTerm</i>.
+
+All of these apps should just be detected correctly, no matter their location on your system. If you can open it using `open -a "appname"`, the app should be detected and work. If you have renamed the app, there might be an issue getting it detected.
+
+To see which files are checked to determine availability, see [this file](./phpmon/Domain/Helpers/Application.swift).
+
+You can add your own apps by creating and editing a `~/.phpmon.conf.json` file, with the following entry:
+
+<pre>
+{
+    "scan_apps": ["Xcode", "Kraken"]
+}
+</pre>
+
+You can put as many apps as you'd like in the `scan_apps` array, and PHP Monitor will check for the existence of these apps. You do not need to set the full path, just the name of the app should work. Not all apps support opening a folder, though, so your success might vary.

+
+There's an Alfred workflow usually included in the release list, you can grab it by going to releases and downloading the asset `phpmon.alfredworkflow`.
+
+If you'd like to integrate something yourself, all you need to to is use the `phpmon://` protocol and ensure that third party app integrations are enabled in Preferences (in PHP Monitor).
+
+Using app callbacks, macOS and PHP Monitor allow for the following to be called:
+
+* phpmon://list
+* phpmon://services/stop
+* phpmon://services/restart/all
+* phpmon://services/restart/nginx

+
+<details>
+<summary><strong>How does the app know what PHP version is required for my app?</strong></summary>
+
+The `composer.json` file in the root of the folder (if it exists) is scanned and interpreted.
+
+If the version is set in `platform`, it takes precendence.
+If the version is not set in `platform` but it is in `require` (most common) then that version is used.

+
+<details>
+<summary><strong>What do the checkmarks next to the PHP version mean in the site list?</strong></summary>
+
+You'll see a checkmark next to the version number if the currently enabled PHP version is compatible with the version required to run the site. 
+
+This is determined by evaluating the PHP requirement constraint (e.g. `^8.0`, `~8.0` or a specific version: `8.0`).

+<summary><strong>Why can't I see the driver type any more? It says "Project Type" now.</strong></summary>
+
+PHP Monitor currently checks your `composer.json` file to try to figure out what project you are running. 
+
+This approach is a lot faster than asking for a driver when you have many sites linked, but is slightly less reliable since the framework or type of project inferred via `composer.json` might not be 100% accurate.
+
+You can always still ask Valet using the command line, should it be necessary. In my experience fetching the drivers slowed down the app unnecessarily.

 This utility will detect which PHP versions you have installed via Homebrew, and then allows you to switch between them.
 
-This means:
+The switcher will disable all PHP-FPM services not belonging to the version you wish to use, and link the desired version of PHP. Then, it'll restart your desired PHP version's FPM process. This all happens in parallel, so this should be much faster than Valet’s switcher.
 
-- You have at least the latest version of PHP installed (`php`)
-- You have installed Laravel Valet (`which valet` returns `/usr/local/bin/valet`)
-- You ran `valet trust`, which means Valet commands can be run without using sudo
+### Config change detection
 
-The utility runs the following commands:
+PHP Monitor watches your filesystem in the relevant `conf.d` directory for the currently linked PHP version. 
 
-- Unlink all detected PHP versions & stop the respective `php@X.X` services
-- Link the desired version of PHP, and start the associated service
+Whenever an .ini file is modified, PHP Monitor will attempt to reload the current information about the active PHP installation. 
+
+If an extension or other process writes to a single file a bunch of times in a short span of time (&lt; 1 sec), PHP Monitor will only reload the active configuration information after a while (with a slight delay).
+
+### Site detection
+
+1. **Location of your sites**: PHP Monitor uses the Valet configuration file to determine which folders to look into. Each folder is scanned and then PHP Monitor will validate if a composer.json file exists to determine the desired PHP version.
+1. **Sites secured or not secured**: Whether the directory has been secured is determined by checking if a matching certificate exists under Valet's `Certificates` directory for that site name.
+1. **Project type**: PHP Monitor checks your `composer.json` file for "notable dependencies". If you have `laravel/framework` in your `require`, there's a good chance the project type is `Laravel`, after all.
+
+*Note*: If you have linked a folder in Documents, Desktop or Downloads you might need to grant PHP Monitor access to those directories for PHP Monitor to work correctly.

+I have done my best to annotate as much as humanly possible, and have avoided using an overly complicated architecture to keep the code as easy to maintain as possible. The code isn't perfect by a long shot (lots of cleanup can still happen!) but the application works well.

+     More information on these constraints can be found here:
+     https://getcomposer.org/doc/articles/versions.md#writing-version-constraints
+     
+     - 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
+     always going to pass.
+     
+     **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.)
