 # HyperionOS
 
+HyperionOS is a modular, hybrid kernel operating system written entirely in Lua. It features a custom task scheduler, virtual filesystem, syscall interface, and separates core functionality from user-space services.
+
 ---
-# Desclaimer
+
-To build
+## Building
+
+See `building.md`.
+
+---
+
+## Features
+
+- Functionality is split into kernel modules (`.kmod`)
+- Task-based lightweight thread/task preemptive scheduler with process isolation and IPC support
+- Virtual filesystem unified interface for disk, RAM, and virtual filesystems
+- TTY & Shell
+
+---
+
+## Kernel Modules
+
+Modules are loaded in priority order from `/lib/modules/`.
+
+You can add your own `.kmod` files to extend kernel functionality without modifying the core.
+
+---
+
+## Debugging & Logging
+
+The kernel logs to `/var/log/syslog.log` during runtime.
+you can add to it by doing `syscall.log(text, tag, color)`
+
+---
+
+## Contributing
+
+Contributions are welcome, though please follow these guidelines:
+
+1. No AI-generated kernel code, keep the core human written.
+2. Modularize, new features should go into kernel modules where possible.
+3. Document, update comments and docs when adding/changing functionality.
+4. Test, ensure your changes don’t break existing functionality.
+
+Add your name to `contributors.md` when your PR is merged.
