 Unlike other GDB plugins, GEF has an extensive and up-to-date
 [documentation](https://hugsy.github.io/gef/). Users are recommended to refer to it as it may help
 them in their attempts to use GEF. In particular, new users should navigate through it (see the
 [FAQ](https://hugsy.github.io/gef/faq/) for common installation problems), and the problem persists,
 try to reach out for help on the Discord channel or submit an issue.
