+# Contributing
+
+This document provides guidelines for contributing to the module.
+
+## Dependencies
+
+The following dependencies must be installed on the development system:
+
+- [Docker Engine][docker-engine]
+- [Google Cloud SDK][google-cloud-sdk]
+- [make]
+
+## Generating Documentation for Inputs and Outputs
+
+The Inputs and Outputs tables in the READMEs of the root module,
+submodules, and example modules are automatically generated based on
+the `variables` and `outputs` of the respective modules. These tables
+must be refreshed if the module interfaces are changed.
+
+### Execution
+
+Run `make generate_docs` to generate new Inputs and Outputs tables.
+
+## Integration Testing
+
+Integration tests are used to verify the behaviour of the root module,
+submodules, and example modules. Additions, changes, and fixes should
+be accompanied with tests.
+
+The integration tests are run using [Kitchen][kitchen],
+[Kitchen-Terraform][kitchen-terraform], and [InSpec][inspec]. These
+tools are packaged within a Docker image for convenience.
+
+The general strategy for these tests is to verify the behaviour of the
+[example modules](./examples/), thus ensuring that the root module,
+submodules, and example modules are all functionally correct.
+
+### Test Environment
+The easiest way to test the module is in an isolated test project. The setup for such a project is defined in [test/setup](./test/setup/) directory.
+
+To use this setup, you need a service account with Project Creator access on a folder. Export the Service Account credentials to your environment like so:
+
+```
+export SERVICE_ACCOUNT_JSON=$(< credentials.json)
+```
+
+You will also need to set a few environment variables:
+```
+export TF_VAR_project_id="project_id_of_test_project"
+export TF_VAR_parent_resource_project="project_id_of_test_project"
+export TF_VAR_parent_resource_folder="folder_id_of_test_folder"
+export TF_VAR_parent_resource_organization="org_id_of_test_organization"
+export TF_VAR_parent_resource_billing_account="billing_account_id_of_test_billing_account"
+```
+
+With these settings in place, you can prepare a test project using Docker:
+```
+make docker_test_prepare
+```
+
+### Noninteractive Execution
+
+Run `make docker_test_integration` to test all of the example modules
+noninteractively, using the prepared test project.
+
+### Interactive Execution
+
+1. Run `make docker_run` to start the testing Docker container in
+   interactive mode.
+
+1. Run `kitchen_do create <EXAMPLE_NAME>` to initialize the working
+   directory for an example module.
+
+1. Run `kitchen_do converge <EXAMPLE_NAME>` to apply the example module.
+
+1. Run `kitchen_do verify <EXAMPLE_NAME>` to test the example module.
+
+1. Run `kitchen_do destroy <EXAMPLE_NAME>` to destroy the example module
+   state.
+
+## Linting and Formatting
+
+Many of the files in the repository can be linted or formatted to
+maintain a standard of quality.
+
+### Execution
+
+Run `make docker_test_lint`.
