-In a separate terminal, start TestRPC (a convenience command is provided as part of the [0x.js monorepo](https://github.com/0xProject/0x-monorepo))
-
-```bash
-cd ../..
-yarn testrpc

+## Migrations
+
+Migrate the 0x system of smart contracts on the network of your choice using these migrations.
+
+## 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
+
+If this is your **first** time building this package, you must first build **all** packages within the monorepo. This is because packages that depend on other packages located inside this monorepo are symlinked when run from **within** the monorepo. This allows you to make changes across multiple packages without first publishing dependent packages to NPM. To build all packages, run the following from the monorepo root directory:
+
+```bash
+yarn lerna:rebuild
+```
+
+Or continuously rebuild on change:
+
+```bash
+yarn dev
+```
+
+You can also build this specific package by running the following from within its directory:
+
+```bash
+yarn build
+```
+
+or continuously rebuild on change:
+
+```bash
+yarn build:watch
+```
+
+### Clean
+
+```bash
+yarn clean
+```
+
+### Lint
+
+```bash
+yarn lint
+```
+
+### Migrate
+
+In order to migrate the 0x smart contracts to TestRPC/Ganache running at `http://localhost:8545`, run:
+
+```bash
+yarn migrate
+```
