+# Dotfiles
+
+Hello, welcome to my dotfiles repository.
+
+I have grown to believe that dotfiles is among the most unfiltered
+expressions of a person. Here are mine. This repository obviously
+helps me sync configuration across different machines, but I do
+also hope that it comes in handy to another stranger. To that end,
+I shall maintain an Index *(edit: **attempt to**)* of the dotfiles
+in this repository and where that might fit on your own machine.
