+### Editor setup
+
+Some configuration is shared by every editor, so you rarely need to set anything up by hand:
+
+- [`.editorconfig`](https://editorconfig.org) holds the whitespace rules (4 spaces for Python, 2 for TypeScript/JSON/YAML, LF line endings, final newline). Most editors read it natively or through a plugin.
+- `[tool.pyright]` in `pyproject.toml` points Pyright, basedpyright and Pylance at the `.venv` created by `uv sync` and at the repository root for imports.
+- `.ruff.toml`, `frontend/eslint.config.js` and `frontend/prettier.config.cjs` are picked up by the matching editor integrations.
+
+Editor-specific configuration that is tracked:
+
+- **VS Code:** `.vscode/launch.json` has debug targets for the API, the Celery worker and the frontend.
+- **Zed:** open the repository root (not `frontend/`). `.zed/settings.json` configures the language servers and formatters, `.zed/tasks.json` adds tasks (`task: spawn`) for the dev services, the API, the worker, the frontend, tests and linting, and `.zed/debug.json` adds debug targets (`debugger: start`). Python files are not formatted on save because most of the tree is not `ruff format` clean; frontend files are, with ESLint fixes followed by Prettier, as in the pre-commit hook. Project settings cannot install extensions, so if you want the matching syntax support add this to your own Zed settings:
+
+    ```json
+    {
+      "auto_install_extensions": {
+        "dockerfile": true,
+        "docker-compose": true,
+        "toml": true,
+        "mdx": true
+      }
+    }
+    ```
+
+Personal preferences belong in your user settings; `.vscode/settings.json` and any other file under `.zed/` are ignored by git.
