+The tldr project is a collection of community-maintained help pages for command-line tools, that aims to be a simpler, more approachable complement to traditional man pages.
+
+Run it by typing "tldr <command>" into terminal.
+
+Maybe you are new to the command-line world? Or just a little rusty? Or perhaps you can't always remember the arguments to lsof, or tar?
+
+It also is more digestable than man pages which blasts pages of useless stuff at you every time you use it.
