+# Cannot output to /public
+
+#### Why This Error Occurred
+
+Either you set `distDir` to `public` in your `next.config.js` or during `next export` you tried to export to the `public` directory.
+
+This is not allowed due to `public` being a special folder in Next.js used to serve static assets.
+
+#### Possible Ways to Fix It
+
+Use a different `distDir` or export to a different folder.

 #### Why This Error Occurred
 
-While auto exporting a page a valid React Component wasn't found. This could mean you have a file in `pages` that exports something that is not a React Component.
+A page that does not export a valid React Component was found while analyzing the build output.
+
+This is a hard error because the page would error when rendered, and causes poor build performance.
 
 #### Possible Ways to Fix It
 
-Move any non-page files that don't export a React Component as the default export to a different folder like `components` or `lib`.
+Investigate the list of page(s) specified in the error message.
+For each, you'll want to check if the file is meant to be a page.
+
+If the file is not meant to be a page, and instead, is a shared component or file, move the file to a different folder like `components` or `lib`.
+
+If the file is meant to be a page, double check you have an `export default` with the React Component instead of an `export`. If you're already using `export default`, make sure the returned valid is a valid React Component.

+# Static directory is deprecated
+
+#### Why This Error Occurred
+
+In versions prior to 9.0.6 the `static` directory was used to serve static assets in a Next.js application. This has been deprecated in favor of a `public` directory.
+
+The reason we want to support a `public` directory instead is to not require the `/static` prefix for assets anymore and there is no reason to maintain both paths.
+
+#### Possible Ways to Fix It
+
+You can move your `static` directory inside of the `public` directory and all URLs will remain the same as they were before.
+
