 # .lua-files
 It's like dotfiles, but no, it's just Lua scripts I find useful.
+
+## Installation
+1. Put this folder somewhere.
+2. Add that somewhere to your path. (On Windows, search for Environment Variables (it's "part of" Control Panel) and use the UI to add them to System variables.)
+3. (On Windows) Add `.LUA` to PATHEXT.
