+## Original pattern/approach and some key config logic
+
+The original pattern and approach for this project, the program-installation scripts and
+logic, the copy-configs-and-scripts scripts and logic, the "tmux sessionizer" (tmux
+session init logic), my initial neovim and tmux configs, and my general workflow/workspace
+strategy, were derived from several of ThePrimeagen's projects and videos, including a
+FrontEnd Masters course which he taught (each are listed below). I was unable to locate
+any required licenses or copyrights for the code contained within these sources, but I
+wanted to give attribution nonetheless.

+## Idea of using a list of programs in a file for build/install
+
+The idea of using a file with a list of programs in it to build and/or install was inspired by Luke Smith's [LARBS project](https://github.com/LukeSmithxyz/LARBS/tree/master).
