 # Bread Ecosystem
 
-Welcome to the **Bread Ecosystem**!
+A collection of Rust tools for the Linux desktop (Hyprland / Wayland / Arch).
+Install any product with a single command — no Rust toolchain required.
 
-This repository contains the core components and tools for the Bread Ecosystem, primarily focused on package management and theming.
+```sh
+curl https://breadway.dev/get | sh
+bakery install breadbar
+```
 
-## Workspace Members
+## Products
 
-This Rust workspace contains the following crates:
+| Package | Description |
+|---------|-------------|
+| `bread` | Reactive automation daemon (`breadd`) + CLI |
+| `breadbar` | Status bar and notification daemon |
+| `breadbox` | Cloud sync daemon (`breadbox-sync`) + file browser |
+| `breadcrumbs` | Network information CLI |
+| `breadpad` | Scratchpad / quick-note app |
 
-- **[`bakery`](./bakery)**: The package manager for the Bread Ecosystem.
+## Installing bakery
-- **[`bread-theme`](./bread-theme)**: A shared theming crate integrating pywal and Catppuccin for the Bread Ecosystem, with optional support for GTK4 and Wayland.
+
+`bakery` is the package manager for the ecosystem. Install it with the bootstrap script:
+
+```sh
+curl https://breadway.dev/get | sh
+# or
+curl -sSfL https://get.breadway.dev | sh
+```
+
+The script downloads the prebuilt `bakery` binary to `~/.local/bin/bakery` and prints a note if that directory isn't on your `PATH` yet.
+
+## Using bakery
+
+```sh
+bakery list                    # all available packages
+bakery list --installed        # only installed packages
+bakery info breadbar           # version, binaries, system deps, services
+bakery doctor                  # check system deps for installed packages
+bakery doctor breadbar         # check system deps for a specific package
+
+bakery install <pkg>           # install a package
+bakery update <pkg>            # update a package
+bakery update --all            # update everything
+bakery remove <pkg>            # remove a package (data files are never deleted)
+```
+
+`bakery install` runs `doctor` first and bails with a clear message if any system dependency is missing. Binaries land in `~/.local/bin` (override with `BAKERY_BIN_DIR`).
+
+## System dependencies by product
+
+| Package | Arch packages |
+|---------|--------------|
+| `bread` | `libudev` `dbus` |
+| `breadbar` | `gtk4` `gtk4-layer-shell` `dbus` `iw` |
+| `breadbox` | `gtk4` `librsvg` `dbus` |
+| `breadcrumbs` | `networkmanager` |
+| `breadpad` | `gtk4` `dbus` |
+
+## Theming
+
+All GUI products (breadbar, breadbox, breadpad) read pywal colors from
+`~/.cache/wal/colors.json` and fall back to Catppuccin Mocha when that file
+is absent. Per-app CSS overrides live at `~/.config/<app>/style.css`.
+
+The shared theming logic lives in the `bread-theme` crate in this repo.
+
+## Workspace
+
+This repo is a Cargo workspace:
+
+```
+bread-ecosystem/
+├── bakery/          # package manager binary
+├── bread-theme/     # shared pywal + Catppuccin theming crate
+├── registry/        # bread-ecosystem.toml — product registry
+└── scripts/
+    ├── get.sh       # curl | sh bootstrap
+    └── gen-index.sh # generates dl.breadway.dev/index.json from release artifacts
+```
+
+## Release pipeline
+
+Each product repo (`Breadway/bread`, `Breadway/breadbar`, …) has a
+`.github/workflows/release.yml` that triggers on `v*` tags. The workflow
+runs on a self-hosted runner on hestia, builds a stripped x86_64 binary,
+deposits it at `dl.breadway.dev/<pkg>/<version>/`, updates `index.json`,
+and mirrors the binary to GitHub Releases as a fallback.
+
+`bakery` always tries `dl.breadway.dev` first and transparently falls back
+to the GitHub Release URL recorded in the manifest.
