+# metrics
+
+This is a template for an OpenSAFELY Core repository.
+
+Put your project description here.
+
+New repo checklist:
+- [ ] Does the repo require a Dockerfile?
+  If not, delete:
+  - Dockerfile -
+  - .dockerignore
+  - hadolint pre-commit hook from `.pre-commit-config.yaml`
+  - `lint-dockerfile` action from `.github/workflows/main.yml`
+- [ ] Is this a Django project?
+  If so, you probably need to add the following per-file ignores to `.flake8`
+  ```
+  per-file-ignores =
+    manage.py:INP001
+    gunicorn.conf.py:INP001
+  ```
+- [ ] Will this project be installed with pip?
+  If so, delete `requirements.prod.in` and switch references in the `justfile` to `pyproject.toml`
+- [ ] Update DEVELOPERS.md with any project-specific requirements and commands
+- [ ] Update commands in `justfile`
+
+
+## Developer docs
+
+Please see the [additional information](DEVELOPERS.md).
