+# Contributing
+
+## Terms
+
+This contributor guide is mainly for Zapier employees. However, zapier-platform is a
+public repo. Everyone is welcome to submit a pull request (PR). For non-employees, you
+must agree to the terms of service listed on https://zapier.com/platform/tos or the
+[LICENSE][license] file of the repo before contributing.
+
+## Local Setup
+
+Install [Yarn][yarn] if you haven't. We use Yarn to manage packages.
+
+Clone this repo with git:
+
+```bash
+git clone [email protected]:zapier/zapier-platform.git
+cd zapier-platform
+```
+
+In the repo directory, install dependencies with yarn:
+
+```bash
+yarn
+```
+
+That's it! Now you have a local environment for development.
+
+## Running Tests
+
+You can run all tests for all packages with yarn test:
+
+```bash
+yarn test
+```
+
+You seldom need to run all the tests because we have [CI][ci] do it. You have several ways to
+filter running tests.
+
+### Running All Tests in a Package
+
+To run tests for a single package, you go into the package directory and run yarn test.
+For example, this is how you run all the tests for the cli package:
+
+```bash
+cd packages/cli
+yarn test
+```
+
+### Using .only
+
+TBA
+
+## Releasing a New Version
