+## CDN Proxy
+
+In most cases, Nuxt can work with third-party content that is not generated or created by Nuxt itself. But sometimes such content can cause problems, especially Cloudflare's "Minification and Security Options".
+
+Accordingly, you should make sure that the following options are unchecked / disabled in Cloudflare. Otherwise, unnecessary re-rendering or hydration errors could impact your production application.
+
+1. Speed > Optimization > Auto Minify: Uncheck JavaScript, CSS and HTML
+2. Speed > Optimization > Disable "Rocket Loader™"
+3. Speed > Optimization > Disable "Mirage"
+4. Scrape Shield > Disable "Email Address Obfuscation"
+5. Scrape Shield > Disable "Server-side Excludes"
+
+With these settings, you can be sure that Cloudflare won't inject scripts into your Nuxt application that may cause unwanted side effects.
