+### Vue support
+
+`eslint-plugin-header` now supports `.vue` files. Please see installation instructions for [eslint-plugin-vue](https://eslint.vuejs.org/user-guide/) before trying to integrate with `eslint-plugin-header`. There are some caveats to be aware of:
+* `<script>` tag must be defined within a `.vue` file, otherwise the linter will crash.
+* `<script>` tag must be defined at the top of a `.vue` file, otherwise the linter won't realize the comment is in the file and will inject it multiple times.
+* `<script>` tag must contain at least `export default {
+    name: 'component-name'
+}` otherwise the linter won't realize the comment is in the file and will inject it multiple times.
+
+It is suggested to use `vue/component-tags-order` rule in parallel to ensure `<script>` tags are at the top of each `.vue` file (part of `eslint-plugin-vue`, see [eslint-plugin-vue/component-tags-order](https://github.com/vuejs/eslint-plugin-vue/blob/master/docs/rules/component-tags-order.md) for more information):
