+> disallow use of v-text
+
+- :wrench: The `--fix` option on the [command line](https://eslint.org/docs/user-guide/command-line-interface#fixing-problems) can automatically fix some of the problems reported by this rule.
+  - However, when using selfClose to element with v-text like `<div v-text="foobar" />`, it can't be fixed.
+
