-**Note:** For versions coming from user-input, you are recommended to truncate the string to a sensible length to prevent abuse. For example, 100 length.
+## Important
+
+If you run the regex against untrusted user input, it's recommended to truncate the string to a sensible length (for example, 100). And if you use this in a server context, you should also [give it a timeout](https://github.com/sindresorhus/super-regex).
