## What it is
TempleOS is a free, public-domain, 64-bit hobby operating system written by Terry A. Davis, featuring its own HolyC language, compiler, and graphics shell. This repository is a final snapshot/mirror of the complete operating system source, preserved after the author's passing.

## Use cases
- explore a complete from-scratch operating system codebase
- learn how a 64-bit bare-metal OS with its own compiler works
- run a self-contained OS with its own HolyC programming language in a VM
- study a single-arch, ring-0-only OS design with no security boundaries
- preserve and research the work of Terry A. Davis

## When to choose
- you want to read or study the full source of a complete hobby operating system
- you need the canonical public-domain TempleOS snapshot for archival or research
- you want to experiment with HolyC and TempleOS's built-in compiler and graphics in a VM

## When to avoid
- you need a production, secure, or maintained operating system
- you expect driver support, networking, or multi-user security
- you want an actively developed project with community support or a license file

## Facets
- artifact type: application
- maturity: abandoned
- function: interpreter, compiler, graphics, developer-tools
- domain: operating-systems, developer-tools, programming-languages, education
