+## Adding and upgrading plugins
+
+When adding or upgrading a plugin, we should see changes in both `package.json`
+and `yarn.lock`.
+
+Make sure to run `make image` before running these commands.
+
+Add a plugin:
+
+```
+bin/yarn add eslint-config-google
+```
+
+Upgrade a plugin:
+
+```
+bin/yarn upgrade eslint-config-google
+```
+
+## Testing Changes
+
+Changes made to the engine can be tested locally.
+
+1. Install [the CodeClimate CLI](https://github.com/codeclimate/codeclimate).
+1. Create the image (customizing the `IMAGE_NAME` as needed):
+```bash
+IMAGE_NAME=codeclimate/codeclimate-eslint-test make image
+```
+1. Add the engine to your test `.codeclimate.yml`:
+```yaml
+engines:
+  eslint-test:
+    enabled: true
+```
+1. Run analyze via the CLI:
+```bash
+codeclimate analyze --dev
+```

 ### Installation
 
-1. If you haven't already, [install the Code Climate CLI](https://github.com/codeclimate/codeclimate).
-2. Run `codeclimate engines:enable eslint`. This command both installs the engine and enables it in your `.codeclimate.yml` file.
-3. You're ready to analyze! Browse into your project's folder and run `codeclimate analyze`.

+
+### Configuration
+
+#### `ignore_warnings`
+
+By default, this engine will emit both ESLint errors and warnings as Code
+Climate issues. If you prefer, you can ignore warning-level violations by
+setting the `ignore_warnings` configuration option:
+
+```yaml
+eslint:
+  enabled: true
+  config:
+    ignore_warnings: true
+```
