+| crate-name         | The crate whose API to check for semver                                                                                           |         |
+| crate-target       | By default, check the library target of the crate. To check a different target (e.g. a binary target), set this to `--bin <NAME>` | `--lib` |
+| version-tag-prefix | The prefix to use for the git tag for a version; the default "v" creates tags like "v1.0.0"                                       | `v`       |

 ## Use with a different version tag format
 
 Change the `version-tag-prefix` setting to reflect the prefix used to create the version tag. The setting's default value `'v'` creates version tags like `v1.2.3`.
