 ## Documentation & quickstart
 
-This repository contains only code. See detailed developer and architecture documentation in the [Docs](https://git.allucanget.biz/allucanget/calminer-docs) repository.
+- Detailed developer, architecture, and operations guides live in the companion [calminer-docs](../calminer-docs/) repository. Please see the [README](../calminer-docs/README.md) there for instructions.
+- For a local run, create a `.env` (see `.env.example`), install requirements, then execute `python -m scripts.init_db` followed by `uvicorn main:app --reload`. The initializer is safe to rerun and seeds demo data automatically.
+- To wipe and recreate the schema in development, run `CALMINER_ENV=development python -m scripts.reset_db` before invoking the initializer again.
