I've been playing lots of CTFs lately and there's lot to learn in them and some times the challenges are either repeated or are of similar type so it's better to keep a record of them. So I started making CTF notes.
Then after sometime I started doing HackTheBox, wizardlabs etc to get a good understanding of Pentesting or maybe I am just doing it for fun 😄 With all this going on it's always good to keep notes so I don't spend hours googling the same thing.
With that intention I first decided to just put them in one of my github repository but then I decided to use what the cool people are using so here I am on GitBook
Obviously this idea of keeping notes were taken after I found out how other people maintain their so called idea or learning Notes.
Some good list to check out are:
- 
trailofbit's CTF Guide - A very good guide to get an idea about CTFs and different type of challenges
 
- 
John Hammond's CTF Katana - Really good and short notes.
