+### 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
+
+Build all packages
+
+```bash
+yarn lerna:run build
+```
+
+### Lint
+
+Lint all packages
+
+```bash
+yarn lerna:run lint
+```
+
+### Run Tests
+
+Before running the tests, you will need to spin up a [TestRPC](https://www.npmjs.com/package/ethereumjs-testrpc) instance and deploy all the 0x smart contracts.
+
+In a separate terminal, start TestRPC (a convenience command is provided as part of this repo)
+
+```bash
+yarn testrpc
+```
+
+Then in your main terminal run
+
+```
+cd packages/contracts
+yarn migrate
+cd ..
+```
+
+And finally from the root project directory run
+
+```bash
+yarn lerna:run test
+```
