+# newproject
+
+One command that composes a project from the templates in this organization: `infra` at the root, then `backend-python`, `frontend-svelte` and `caddy` on top, each with its own answers file.
+
+```sh
+newproject ~/projects/my-thing
+```
+
+Templates are read from `$TEMPLATES_DIR` (default `~/projects/templates`). Every part updates independently:
+
+```sh
+copier update -a .copier-answers.backend.yml
+```
+
+Shapes it produces:
+
+- infrastructure only: root `docker-compose.yml`, `Makefile`, `.env`, optional `caddy/`
+- backend with one or many services, each `python -m <module>` from one image
+- backend and frontend as separate containers behind Caddy
+- backend serving the frontend's static build from the api
+- frontend only
