This repository contains most of how my system is built (excluding for now the configs containing secrets).

The system-level configuration lives in the nixos directory, with configuration.nix being the main module and other modules available in the modules subdirectory.

The user-level configuration lives in home-manager and works using Home Manager to configure user files, programs, etc. The main module is home.nix, with additional modules in the modules subdirectory.

All of the above mentioned Nix modules are pieced together in flake.nix which defines

• The inputs --- references to Nix package repositories, and
• The outputs --- NixOS system derivations which include certain modules from the nixos and home-manager directories.

Both the nixos and home-manager directories have a src subdirectory which contains all the "source files" --- mostly configuration files for external programs such as Neovim or Htop. These files are then symlinked against by Nix, which allows to configure all of the user's programs in the same repository and then dynamically reconfigure without rebuilding the system.

The secrets directory contains enciphered secrets related to the configuration. The files are encrypted using the pshash algorithm.
