README.md

@@ -123,6 +123,7 @@ Here are the options you can set in your `.cz-config.js`:
 * **allowCustomScopes**: {boolean, default false}: adds the option `custom` to scope selection so you can still type a scope if you need.
 * **allowBreakingChanges**: {Array of Strings: default none}. List of commit types you would like to the question `breaking change` prompted. Eg.: ['feat', 'fix'].
 * **skipQuestions**: {Array of Strings: default none}. List of questions you want to skip. Eg.: ['body', 'footer'].
+* **skipEmptyScopes**: {boolean, default false}: If a chosen type has no scopes declared, skip the scope question
 * **appendBranchNameToCommitMessage**: If you use `cz-customizable` with `cz-customizable-ghooks`, you can get the branch name automatically appended to the commit message. This is done by a commit hook on `cz-customizable-ghooks`. This option has been added on `cz-customizable-ghooks`, v1.3.0. Default value is `true`.
 * **ticketNumberPrefix**: {string, default 'ISSUES CLOSED:'}: Set custom prefix for footer ticker number.
 * **breakingPrefix**: {string, default 'BREAKING CHANGE:'}: Set a custom prefix for the breaking change block in commit messages.
