{{subst:lusc|User:RedWarn/.js}}

Step 2: Install RedWarn
Click here to open your common.js page.

If the page doesn't exist or is empty, paste the code you just copied into the empty code editor. Otherwise, just paste the code on a new line below all other userscripts you have loaded. A red syntax error mark may show — this is normal. Once you're finished, publish your changes. If you see a message saying "The document contains errors. Are you sure you want to publish?", click "OK" to publish the page.

Congratulations! You've now installed RedWarn. Click 'next' to ensure your RedWarn install is working correctly and continue to the next steps.
