[Help Wanted] Organize this repository

[jaybosamiya]

This repo is no longer just a "reading material only" repository (see #16). We now encompass any and all useful references (including but not limited to articles, blogs, videos, YouTube channels, wargames sites, perpetual CTFs, etc). However, our repository has a large section named "Yet to organize" that we need to start organizing.

If you want to help out, one great way to do so, is to read through any of the articles in the section, figure out which section it belongs to, and make a PR to move it into that section. If none of the current sections are good enough, making a new section may be worth (for example, see #34 in which I requested a new section to be added).

Another way to help out is to provide a short 1-line description of any of the links. This way, we can understand what it is about at a glance.

Over time, we want this to become the one resource that people can look up to find anything useful.
