+**This directory is not required, you can delete it if you don't want to use it.**
+
+This directory contains your static files.
+Each file inside this directory is mapped to `/`.
+Thus you'd want to delete this README.md before deploying to production.
+
+Example: `/static/robots.txt` is mapped as `/robots.txt`.
+
+More information about the usage of this directory in [the documentation](https://nuxtjs.org/guide/assets#static).
