-# dotfiles, plus scripts for box setup
+# dotfiles, plus install/set-up scripts
+
+This repo contains a collection of scripts and files related to:
+
+- configuration (i.e. this serves as my dotfiles repo)
+- installation of programs
+- scripts/executables for my local systems
+- anything else related to getting my boxes (computers) set up as desired
+
+This repo grew into more than I originally intended, but it turned into a fun little
+excursion into the realm of shell scripting (and an intro to Lua for the neovim
+portions).
