+## Project structure
+
+- `goldboot/src/builder/os/` — one module per supported OS
+- `goldboot/src/builder/options/` — shared config types (`Locale`, `Timezone`,
+  `Ntp`, `Packages`, `UnixUsers`, etc.)
+- `goldboot-image/` — image format library
+- `goldboot-macros/` — proc macros (`#[Os(...)]`, `#[derive(Prompt)]`)
+
+## Adding a new OS
+
+1. Create `goldboot/src/builder/os/<name>/mod.rs`.
+2. Annotate the struct with `#[goldboot_macros::Os(architectures(...))]` and
+   derive
+   `Clone, Serialize, Deserialize, Validate, Debug, SmartDefault, goldboot_macros::Prompt`.
+3. Use shared option types from `builder::options` where applicable (hostname,
+   locale, timezone, ntp, packages, unix_users, root_password, iso, size, arch).
+4. Implement `BuildImage` with a `build()` method. We need to manipulate the VM
+   until we get to a shell so we can finish the install via SSH. Use
+   `wait_text!` to wait for the given text to be displayed on the screen.
+5. Register the module in `goldboot/src/builder/os/mod.rs`.
+
+## Updating for a new upstream OS release
+
+1. **Add the new release variant** to the release enum (e.g. `V3_24`,
+   `Bookworm`) at the top of the enum so it sorts newest-first.
+2. **Keep EOL releases**
+3. **Update the default variant** to the newest stable release.
+4. **Update the default ISO** — find the new ISO filename, URL, and sha256
+   checksum from the upstream mirror and update the `#[default(Iso { ... })]` on
+   the `iso` field.
+5. Run `cargo check` to confirm everything compiles.
+
+### Pop!\_OS (`goldboot/src/builder/os/pop_os/mod.rs`)
+
+Release page: https://pop.system76.com ISO index:
+`https://iso.pop-os.org/<YY.MM>/amd64/<generic|nvidia>/<revision>/` API:
+`https://api.pop-os.org/builds/<YY.MM>/stable?arch=amd64`
+
+**Release enum** — `PopOsRelease` lists LTS releases only, newest-first.
+Pop!\_OS follows Ubuntu's LTS cadence.
+
+Pop!\_OS uses a **custom graphical installer** (not Ubuntu autoinstall).
+Installation is driven by VNC automation in `build()`. Because of this, the
+primary user account must be configured via `user: PopOsUser` — the installer
+requires it. Post-install config (extra users, packages, hostname, timezone) is
+applied over SSH.
+
+### Ubuntu (`goldboot/src/builder/os/ubuntu/mod.rs`)
+
+Release page: https://ubuntu.com/about/release-cycle ISO index:
+https://releases.ubuntu.com/<codename>/SHA256SUMS
+
+**Release enum** — `UbuntuRelease` lists only currently-supported releases. LTS
+releases are preferred; interim releases are included but not the default.
+
+Ubuntu uses **autoinstall** (cloud-init YAML) for unattended installation —
+generated at build time in `Ubuntu::generate_autoinstall()`. There is no static
+config file.
+
+### Debian (`goldboot/src/builder/os/debian/mod.rs`)
+
+Release page: https://www.debian.org/releases/ ISO index:
+https://cdimage.debian.org/cdimage/release/current/amd64/iso-cd/
+
+**Release enum** — `DebianEdition` lists releases stable-first (Trixie,
+Bookworm, Bullseye, Forky, Sid). Stable and oldstable always have real ISOs;
+testing/unstable are opt-in.
+
+The preseed is generated at build time in `Debian::generate_preseed()` — no
+static file to update.
+
+### Alpine Linux (`goldboot/src/builder/os/alpine_linux/mod.rs`)
+
+Release page: https://alpinelinux.org/releases/ CDN root:
+https://dl-cdn.alpinelinux.org/alpine/
+
+**Release enum** — `AlpineRelease` lists supported branches newest-first, with
+`Edge` last. Only include branches that appear on the releases page as actively
+supported.
+
+## TODO list
+
+- Finish registry implementation
+- Create nixpkgs branch for configuring server
+- Figure out how to package goldboot.efi
+- Finish remaining builders
+- Finish multiboot builds
