+## 0x-json-schemas
+
+0x JSON schemas for those developing on top of 0x protocol.
+
+Read the [documentation](http://0x-json-schemas-py.s3-website-us-east-1.amazonaws.com/)
+
+## Installing
+
+```bash
+pip install 0x-json-schemas
+```
+
+## 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 Code and Dependencies
+
+Ensure that you have installed Python >=3.6 and Docker. Then:
+
+```bash
+pip install -e .[dev]
+```
+
+### Test
+
+Tests depend on a running ganache instance with the 0x contracts deployed in it. For convenience, a docker container is provided that has ganache-cli and a snapshot containing the necessary contracts. A shortcut is provided to run that docker container: `./setup.py ganache`. With that running, the tests can be run with `./setup.py test`.
+
+### Clean
+
+`./setup.py clean --all`
+
+### Lint
+
+`./setup.py lint`
+
+### Build Documentation
+
+`./setup.py build_sphinx`
+
+### More
+
+See `./setup.py --help-commands` for more info.
