+### 3: Remove Remix Source Maps 
+
+Remix validly discourages the user to have source maps in production. After uploading the maps to Sentry we suggest you delete the `.map` files, here's a simple example in bash:
+
+```bash
+rm ./public/**/*.map
+rm ./build/**/*.map 
+```

 <Note>
 
 By default, if Sentry can't find the uploaded files it needs, it will attempt to download them from the URLs in the stack trace. To disable this, turn off "Enable JavaScript source fetching" in either your organization's "Security & Privacy" settings or your project's general settings.
