+## @0xproject/metacoin
+
+This is an example project that demonstrates how the many Ethereum dev tools developed by 0x can be used in any Solidity/TS project.
+It supports:
+
+*   Compiling & testing smart contracts
+*   Generating typed contract wrappers
+*   Solidity coverage
+*   Solidity gas profiling
+*   Running tests against Ganache
+*   Running tests against our fork of Geth (it supports snapshotting & time travel)
+
+## Contributing
+
+We welcome improvements and fixes from the wider community! To report bugs within this package, please create an issue in this repository.
+
+Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
+
+### Install dependencies
+
+If you don't have yarn workspaces enabled (Yarn < v1.0) - enable them:
+
+```bash
+yarn config set workspaces-experimental true
+```
+
+Then install dependencies
+
+```bash
+yarn install
+```
+
+### Build
+
+To build this package and all other monorepo packages that it depends on, run the following from the monorepo root directory:
+
+```bash
+PKG=@0xproject/metacoin yarn build
+```
+
+Or continuously rebuild on change:
+
+```bash
+PKG=@0xproject/metacoin yarn watch
+```
+
+### Clean
+
+```bash
+yarn clean
+```
+
+### Lint
+
+```bash
+yarn lint
+```
+
+### Test providers
+
+By default tests run against an in-process Ganache instance. If you want to use Geth you'll need to [start a Geth dev node](https://github.com/0xProject/0x-monorepo/blob/v2-prototype/packages/devnet/README.md) first.
+
+```bash
+cd ../devnet
+docker build -t 0x-devnet .
+docker run -it --rm -p 8501:8501 0x-devnet
+```
+
+This Geth version supports snapshots and time travel. Then - run your tests against it.
+
+```
+TEST_PROVIDER=geth yarn test
+```
+
+### Coverage
+
+```bash
+yarn test:coverage
+yarn coverage:report:html
+```
+
+### Profiling
+
+Please note that traces emitted by ganache have incorrect gas costs so we recommend using Geth for profiling.
+
+```bash
+TEST_PROVIDER=geth yarn test:profile
+```
+
+You'll see a warning that you need to explicitly enable and disable the profiler before and after the block of code you want to profile.
+
+```typescript
+import { profiler } from './utils/profiler';
+profiler.start();
+// Some solidity stuff
+profiler.stop();
+```
