+## IDE Integration
+
+Some IDE integrations of PHPCS will fail to register your ruleset since it doesn't live in your project root. In order
+to rectify this, place phpcs.xml at your project root:
+
+```xml
+<?xml version="1.0"?>
+<ruleset name="Project Rules">
+    <rule ref="WPScholar"/>
+</ruleset>
+```
