**CTF Wiki** is an open source project for cybersecurity enthusiasts that aims to help beginners systematically learn about the Capture The Flag (CTF) competition. CTF is a competitive game originating from the DEFCON Global Hacking Conference. It involves many fields and is extremely challenging. CTF Wiki helps participants better understand and master relevant technologies by organizing and sharing basic and advanced knowledge in all directions of CTF. The project was first submitted on GitHub in October 2016. As the content continues to enrich, it has gradually become an important resource for the security community. The CTF Wiki not only covers the basic knowledge of CTF, but also plans to introduce more security research tools and practical experience to help users stay ahead in the rapidly developing field of security technology. CTF Wiki is an open community project that encourages the free sharing of knowledge and will never be commercialized. Users can participate in and utilize this resource by reading online, participating in project contributions, and using Docker to deploy locally. The project also provides two sister projects: ctf-challenges and ctf-tools, which include CTF topics and tools respectively. By participating in CTF Wiki, users can improve their ability to quickly learn new things, develop a way of thinking about solving problems, and have fun and a sense of accomplishment while exploring security technologies. In a free and open spirit, CTF Wiki is committed to providing a platform for global cybersecurity enthusiasts to learn and communicate.
