 ## Excluding files from deployment
 If there are files or directories to be excluded from deployment, such as tests or editor config files, they can be specified in either a `.distignore` file or a `.gitattributes` file using the `export-ignore` directive. If a `.distignore` file is present, it will be used; if not, the Action will look for a `.gitattributes` file and barring that, will write a basic temporary `.gitattributes` into place before proceeding so that no Git/GitHub-specific files are included.
