Feature: documentation for installation on Visual Studio Code about phpcs-variable-analysis HOT 1 OPEN

That's a good idea! Here's my notes from when I last set this up for VSCode, which may help you for right now, but a proper section of the README would be best.

Visit the extension page for VSCode phpcs and click "Install". Once it has installed, click "Reload" in the VSCode extension window or just reload the window by opening the command palette (command-P) and typing "reload".

Once the extension is installed, there are several ways to add the ruleset to a project. The simplest is probably to add a composer.json file to your project directory, then install following the instructions on the README:

composer require --dev dealerdirect/phpcodesniffer-composer-installer
composer require --dev sirbrillig/phpcs-variable-analysis

Next, create a file like this as a phpcs.xml file in your project directory:

<?xml version="1.0"?>
<ruleset name="MyStandard">
    <rule ref="VariableAnalysis"/>
</ruleset>

After that, it should just work!
