-ComfyUI workflow templates available in the app by clicking the **Workflow** button then the **Browse Templates** button.
+This repo hosts the official ComfyUI workflow templates. The repository now ships a
+**package-per-media** structure:
+
+- `packages/core` – manifest + loader helpers shipped as `comfyui-workflow-templates-core`
+- `packages/media_*` – the actual template JSON + preview assets for each media type
+- `packages/meta` and the root `pyproject.toml` – the `comfyui-workflow-templates` meta package that depends on all others
+
+Most contributors only touch the `templates/` folder and `bundles.json`, but the build
+pipeline now requires the helper scripts described below. See the sections on "Adding
+new templates" and "Publishing" for the exact steps.

+Each template lives in one bundle (`media-image`, `media-video`, etc.). Update
+[`bundles.json`](bundles.json) with the template ID so the correct media package ships it.
+After editing `templates/` or `bundles.json`, regenerate the manifest and copy assets into
