+# Agoric Local Chain with docker-compose
+
+To start a local agoric blockchain:
+
+```sh
+docker compose up -d
+```
+
+**NOTE**: The image, which is several Gb, has to be pulled
+and extracted the first time you start the docker application
+services.
+
+Then use `docker-compose logs` etc. as usual.
+
+Some useful recipies are included in `Makefile`.
+Use `yarn make:help` to list them.
+For example: `yarn docker:make mint4k`.

+# Agoric Dapp Starter: Agoric Basics
+
+This is a simple app for the [Agoric smart contract platform](https://docs.agoric.com/).

+<img alt="Vite + React + Agoric page with Connect Wallet button"
+style="border: 1px solid" width="300"
+src="https://docs.agoric.com/assets/img/new_002_small2.2dfb7462.png" />
+
+The contract lets you make an offer to give a small amount of [IST](https://inter.trade/) in exchange for
+a few NFTs.
+
+## Getting started
+
+See [Your First Agoric Dapp](https://docs.agoric.com/guides/getting-started/) tutorial.
+
+## Contributing: Development, Testing
+
+The UI is a React app started with the [vite](https://vitejs.dev/) `react-ts` template.
+On top of that, we add
+
+- Watching [blockchain state queries](https://docs.agoric.com/guides/getting-started/contract-rpc.html#querying-vstorage)
+- [Signing and sending offers](https://docs.agoric.com/guides/getting-started/contract-rpc.html#signing-and-broadcasting-offers)
+
+See [CONTRIBUTING](./CONTRIBUTING.md) for more on testing.
