 * **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.
-* **footerPrefix**: {string, default 'ISSUES CLOSED:'}: Set a custom prefix for the footer block in commit messages.
+* **footerPrefix**: {string, default 'ISSUES CLOSED:'}: Set a custom prefix for the footer block in commit messages. Set to empty string to remove prefix.
