Kali Linux is an open-source, Debian-based Linux distribution geared towards various information security tasks, such as Penetration Testing, Security Research, Computer Forensics and Reverse Engineering.

IF YOU ASK QUESTIONS ABOUT KALI LINUX IN THE DISCORD WITHOUT HAVING READ THE DOCUMENTATION OF THE HACKBERRY AND OF KALI LINUX, YOU ARE A MASSIVE NOOB AND EVERYONE WILL CONSIDER YOU A SKID.
Hacking is 80% intelligence gathering (i.e. googling your problem) and 20% experience. If you fail at this, reconsider if Kali Linux is right for you.
Do not run Kali as your main OS. You have been warned!
