This is the famous escape the matrix article from the hidden wiki. Since most mirrors are down and on the hidden wiki itself, the first chaper was replaced with a bitcoin scam, I thought I repost this here. Copyright goes to the original author and I'm not stating any opinion on this text except that it may or may not be an interesting read ;)

The .txt version is taken from here (there's also an intepretation where that came from), the markdown version was converted via some regexes by, well, me.

Have fun :)
