+## Continuous Integration
+
+`inso` has been designed to run in a CI environment, disabling prompts and providing exit codes to pass or fail the CI workflow accordingly. An example workflow run in Github Actions is as follows. This example will checkout > install NodeJS > install inso > run linting > run unit tests > generate configuration. If any of these steps fail, the GH workflow will as well.
+
+```yaml
+# .github/workflows/test.yml
