-One part alone is rendered at the root of the project; two parts live in `backend/` and `frontend/`. After rendering, `make env` creates `.env` and every `docker-compose.override.yml` from their examples. `updateproject` needs a clean working tree and commits each part's update separately, refreshing `uv.lock` and `bun.lock` first, so the next part starts from a clean tree again. When copier leaves conflicts it stops before committing and lists the files: resolve, commit, run it again. Templates are cloned from `https://git.kotikot.com/templates` unless `TEMPLATES_DIR` points at a directory with local checkouts; `TEMPLATES_REF=HEAD` renders their working trees instead of the latest tag.

+Run in the project directory. It creates the repo if it does not exist (private, `main` as the default branch, the description from `.copier/infra.yml`), adds it as `origin` over ssh, and when the repo is still empty and there are local commits, pushes `main` and `dev` and switches to `dev`. An existing `origin` that points elsewhere is left alone. When the repo already has commits and the project has none yet (a fresh `newproject` for code that lives in Gitea already), the project lands on top of it: the repo's history becomes the local one, the rendered files stay as uncommitted changes against it, and files the templates do not render come back as they are in the repo. Review with `git status` and `git diff`, keep what is yours, commit the rest. `newproject` asks for the organization at the end, or takes `--repo org/name`; without a terminal and without `--repo` it creates nothing.
 
 The organization defaults to `org` from the config, else to the name of the parent directory when it matches an organization. `~/.config/templates/config.toml`:
