+# enforce order of attributes (vue/attributes-order)
+
+## :book: Rule Details
+
+This rule aims to enfore ordering of component attributes. The default order is specified in the [Vue styleguide](https://vuejs.org/v2/style-guide/#Element-attribute-order-recommended) and is:
+- DEFINITION
+ex: 'is'
+- LIST_RENDERING
+ex: 'v-for item in items'
+- CONDITIONALS
+ex: 'v-if', 'v-else-if', 'v-else', 'v-show', 'v-cloak'
+- RENDER_MODIFIERS
+ex: 'v-once', 'v-pre'
+- GLOBAL
+ex: 'id'
+- UNIQUE
+ex: 'ref', 'key', 'slot'
+- BINDING
+ex: 'v-model', 'v-bind'
+- OTHER_ATTR
+ex: 'customProp="foo"'
+- EVENTS
+ex: '@click="functionCall"'
+- CONTENT
+ex: 'v-text', 'v-html'
+
+:+1: Examples of **correct** code`:
+
+```html
+<div
+  is="header"
+  v-for="item in items"
+  v-if="!visible"
+  v-once id="uniqueID"
+  ref="header"
