 Balto is Smart and Fast:
 
-* Installs _your_ versions of eslint and eslint plugins (optionally)
 * _Only_ runs on files that have changed
 * _Only_ annotates lines that have changed
 
-## Requirements
-
-* Default configuration of `dependencyInstallMode` requires `yarn` to be used
-  * If you use npm you will need to set `dependencyInstallMode` to `'none'` and
-    handle the install yourself.

-| `extensions` | A comma separated list of extensions to run ESLint on | no | `"js"` |

+| `failure-level` | The lowest annotation level to fail on ("warning or "error"") | no | `"error"` |

-## A note about permissions
+## Contributing
 
-Because some tools, like [dependabot](https://github.com/dependabot), use tokens for actions that have read-only permissions, you'll need to elevate its permissions for this action to work with those sorts of tools. If you don't use any of those tools, and your workflow will only run when users with permissions in your repo create and update pull requests, you may not need these explicit permissions at all.
+1. Install [devbox](https://www.jetify.com/devbox/)
+2. `devbox setup`
+3. `devbox test`
 
-When defining any permissions in a workflow or job, you need to explicitly include any permission the action needs. In the sample config above, we explicitly give `write` permissons to the [checks API](https://docs.github.com/en/rest/checks/runs) for the job that includes balto-eslint as a step. Because balto-eslint uses [check runs](https://docs.github.com/en/rest/guides/getting-started-with-the-checks-api), the `GITHUB_TOKEN` used in an action must have permissions to create a `check run`. You'll also need `contents: read` for `actions/checkout` to be able to clone the code.
+This will simulate a balto workflow like the above sample config that you can
+inspect for accuracy. At time of writing, there are not automated tests (PRs
+welcome!).
