-This rule is aimed at preventing duplicated property names.
+This rule prevents duplicate `props`/`data`/`methods`/etc. key names defined on a component.
+Even if a key name does not conflict in the `<script>` tag itself, it still may lead to a conflict in the `<template>` since Vue allows directly accessing these keys from there.
