+# Laser Everything Database
+
+Monorepo for the Laser Everything database application and its supporting
+services.
+
+## Components
+
+- `app/` — main Next.js application
+- `bgbye/` — customized background-removal service
+- `dashboard/` — static application dashboard
+- `svgnest/` — customized SVG nesting application
+- `app/files/` — curated manuals, reference material, software and projects
+- `docker-compose.yml` — production service definition
+
+## Runtime data excluded from Git
+
+The following are created or downloaded on the deployment host and are not
+stored in this repository:
+
+- environment and secret files;
+- JavaScript dependencies and Next.js build output;
+- Python virtual environments;
+- BGBye model downloads and caches;
+- logs and temporary files.
+
+The production environment currently expects:
+
+- `app/.env.local`
+- `bgbye/.cache/`
+- `bgbye/.u2net/`
+- `bgbye/.ormbg/`
+
+These must be provisioned separately when deploying a fresh checkout.
+
+## Repository structure
+
+This repository replaces several older nested repositories. BGBye and SVGnest
+are incorporated directly as locally maintained source trees rather than Git
+submodules or automatically updated upstream dependencies. See their
+`UPSTREAM.md` files and `LEGACY_REPOSITORIES.md` for provenance.
