 | `RUNNER_NAME` | The name of the runner to use. Supercedes (overrides) `RUNNER_NAME_PREFIX` |
 | `RUNNER_NAME_PREFIX` | A prefix for a randomly generated name (followed by a random 13 digit string). You must not also provide `RUNNER_NAME`. Defaults to `github-runner` |
 | `ACCESS_TOKEN` | A [github PAT](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) to use to generate `RUNNER_TOKEN` dynamically at container start. Not using this requires a valid `RUNNER_TOKEN` |
-| `RUNNER_SCOPE` | The scope the runner will be registered on. Valid values are `repo`, `org` and `ent`. For 'org' and 'enterprise', `ACCESS_TOKEN` is required and `REPO_URL` is unneccesary. If 'org', requires `ORG_NAME`; if 'enterprise', requires `ENTERPRISE_NAME`. Default is 'repo'. |
+| `RUNNER_SCOPE` | The scope the runner will be registered on. Valid values are `repo`, `org` and `ent`. For 'org' and 'enterprise', `ACCESS_TOKEN` is required and `REPO_URL` is unnecessary. If 'org', requires `ORG_NAME`; if 'enterprise', requires `ENTERPRISE_NAME`. Default is 'repo'. |
 | `ORG_NAME` | The organization name for the runner to register under. Requires `RUNNER_SCOPE` to be 'org'. No default value. |
 | `ENTERPRISE_NAME` | The enterprise name for the runner to register under. Requires `RUNNER_SCOPE` to be 'enterprise'. No default value. |
 | `LABELS` | A comma separated string to indicate the labels. Default is 'default' |
