-Rector - Instant Upgrades and Automated Refactoring
-===================================================
-
-We can use Rector to do some automated refactoring. This is a good way to upgrade your codebase to a new version of PHP.
-
-## Usage
-
-There is basic configuration which includes two costim rules, removing all requires/includes and addid the
-License-header if needed.
-
-```bash
-./vendor/composer/vendor/bin/rector process --config scripts/Rector/basic_rector.php YOUR_DIRECTORY
-```
-
-You can try to update your Code to support PHP 8.0 to 8.2 with the follwoing rule-set:
-
-```bash
-./vendor/composer/vendor/bin/rector process --config scripts/Rector/ilias_9.php YOUR_DIRECTORY
-```
-
-Please check the changes and revert the ones you don't want to have.
-
-The following rule-set contains some general improvements for your code 8such as early returns, removing unused
-variables, etc.):
-
-```bash
-./vendor/composer/vendor/bin/rector process --config scripts/Rector/code_quality.php YOUR_DIRECTORY
-```

-# Rector for ILIAS/Utilities
-
-The ILIAS/Utilities component is an accumulation of many methods and
-classes that have accumulated over the years and unfortunately are often
-widely used across the entire code base. As part of the PHP8 project
-2021/22, large parts of it have been moved to other components as they
-are exclusively or mainly used.
-
-The `ilUtil` class, however, partly contains static methods that cannot
-easily be moved or assigned to another component. partly it also contains
-methods for which alternatives have existed for a long time.
-
-with the help of rector we try to get rid of such places.
-
-# Replace ilUtil:.sendInfo (and 3 more)
-
-There is since at least ILIAS 6 on `ilGlobalTemplateInterface` the method `setOnScreenMessage`, which takes over the
-functionality of the `ilUtil` methods. The rector `ReplaceUtilSendMessageRector` replaces the places that use the static
-ilUtil methods.
-
-Thereby - if not existing - the class is supplemented with an `ilGlobalTemplateInterface` dependency.
-
-Make sure you have a updated composer classmap before running rector!
-
-How to run for a component such as ILIAS/File:
-
-```bash
-./vendor/composer/vendor/bin/rector process --clear-cache --no-diffs --config ./scripts/Rector/ilUtils/ilutil_rector.php components/ILIAS/File
-```
