-# toes-image-builder
-
-Builds a Raspberry Pi Ubuntu Server image for Toes hardware.
-
-## What it does
-
-`build.sh` starts from the Ubuntu 24.04.4 preinstalled ARM64 Raspberry Pi image, mounts it locally, chroots into it, and installs/configures:
-
-- Toes app and systemd service
-- Matter service
-- audio overlay, ALSA config, and audio init service
-- Wi-Fi via `wpa_supplicant` and `systemd-networkd`
-- Bluetooth/Avahi support
-- SSH password login
-- USB serial gadget login
-
-## Requirements
-
-Run on an Ubuntu/Debian host with `sudo` access. On non-ARM64 hosts, the build expects `qemu-aarch64` binfmt support.
-
-Bootstrap the host once:
-
-```sh
-scripts/bootstrap-repo.sh
-```
-
-## Build
-
-```sh
-./build.sh
-```
-
-The script downloads the base image into `cache/`, writes build artifacts into `build/`, mounts the image under `mnt/`, and cleans up mounts on exit.
-
-Final image path:
-
-```text
-build/toes-ubuntu-base.img
-```
-
-## Default image access
-
-- Hostname: `toes`
-- User: `toes`
-- Password: set by `scripts/build-in-chroot.sh`
-- SSH password auth: enabled
-- USB serial gadget: enabled on `ttyGS0`
-
-## Layout
-
-- `build.sh` - top-level build pipeline
-- `scripts/` - host-side build phases
-- `audio/` - audio overlay, ALSA config, and init service
-- `matter/` - Matter systemd service
-- `cache/` - downloaded Ubuntu image and checksums
-- `build/` - generated image files
-- `mnt/` - temporary mount points
-
-## Cleanup
-
-If a build is interrupted and mounts are left behind, run:
-
-```sh
-scripts/cleanup.sh
-```
