@@ -18,6 +18,7 @@ Optional Arguments
 - `file_glob`: If set to true, the `file` argument can be a glob pattern (`asset_name` is ignored in this case) (Default: `false`)
 - `overwrite`: If an asset with the same name already exists, overwrite it (Default: `false`).
 - `promote`: If a prerelease already exists, promote it to a release (Default: `false`).
+- `draft`: Sets the release as a draft instead of publishing it, allowing you to make any edits needed before releasing (Default: `false`).
 - `prerelease`: Mark the release as a pre-release (Default: `false`).
 - `make_latest`: Mark the release as the latest release for the repository (Default: `true`).
 - `release_name`: Explicitly set a release name. (Defaults: implicitly same as `tag` via GitHub API).
