+# sBTC contracts
+
+This folder contains the Clarity contracts and unit tests for
+the sBTC protocol.
+
+## Setup
+
+Install dependencies:
+
+```bash
+pnpm install
+```
+
+## Running tests
+
+```bash
+pnpm test
+```
+
+To run tests in "watch" mode:
+
+```bash
+pnpm vitest
+```
+
+## Generating Clarigen types
+
+This project uses Clarigen to automatically generate types
+for contracts.
+
+When contracts are updated, run:
+
+```bash
+pnpm clarigen
+```
+
+You can also run this in watch mode to automatically generate
+types when contracts are updated:
+
+```bash
+pnpm clarigen --watch
+```
+
+## Contract documentation
+
+Clarigen automatically creates Markdown docs for the contracts
+in this folder. They're located in the [./docs](./docs) folder.
+
+You can re-generate them with:
+
+```bash
+pnpm clarigen docs
+```
