## Overview

Archfetch is a small C11 system-information fetcher. A user runs the program; `src/main.c` loads display settings, gathers system and session details, then formats the values with Arch ASCII art and ANSI colors for terminal output. The sampled code confirms most collectors and their inputs; kernel and configuration behavior is included from the README, tree, and calls in `main.c`, while unsampled implementation details are not inferred.

Main entry points: [`src/main.c`](https://github.com/spectrumdev-tech/archfetch/blob/dev/src/main.c) (Fetch and render), [`src/osinfo.c`](https://github.com/spectrumdev-tech/archfetch/blob/dev/src/osinfo.c) (OS identity), [`src/cpu.c`](https://github.com/spectrumdev-tech/archfetch/blob/dev/src/cpu.c) (CPU details), [`src/config.c`](https://github.com/spectrumdev-tech/archfetch/blob/dev/src/config.c) (Display settings)
