+# Tunic
+
+Install Linux on Windows without a Live USB.
+
+The goal is a program that can install Linux on an existing Windows machine without need of a Live USB or making firmware/BIOS changes.
+
+## Status
+
+This project is pre-alpha quality.
+We do not suggest you use on real hardware; use inside a virtual machine or on a computer you don't care about damaging.
+
+### Requirements
+
+* Windows 10, 64 bit
+* Single unencrypted hard drive hosting the C: volume
+* UEFI
+* At least 4 GB RAM
+* At least 15 GB of free disk space on C:
+* Administrator user permissions
+* Internet access
+
+### Limitations
+
+* Currently, Tunic only installs [Linux Mint with Cinnamon, 64 bit](https://blog.linuxmint.com/?p=3832).
+* We are working on support for Windows 7 and 8, and other Debian/Ubuntu based Linux distros.
+* There are no short term plans for MBR or 32 bit support.
+* Error handling needs improvement.  A failed install could leave the system in an undesirable state.
+
+### What Tunic Does
+
+1. Asks all questions at beginning
+1. Offers full disk overwrite or dual boot arrangement.
+1. If dual boot, shrink C: volume to make space for Linux.  May require reboot.
+1. Download the Linux .iso file
+1. Install Grub with Secure Boot support
+1. Reboot and run the Ubiquity installer, automated
+1. Reboot into Linux!
+
+## Getting Started
+
+### Preparation
+
+Backup your data!
+
+Before you start, make sure to backup up your entire disk(s).
+Tunic does not assist with full disk backup.
+Read disclaimer for more information.
+
+### Usage
+
+1. Download and run the latest .exe file from releases.
+1. Answer questions.
+1. Let it run and walk away.  It can take up to an hour.
+1. Enjoy your new Linux OS!
