My local .editorconfig file

.editorconfig

# Local .editorconfig file.

# This file should only include settings that affect the physical contents of the file, and that you want enforced in the repository, not just how it appears in an editor.
# Do not include personal preference presentation-only settings (such as `indent_size` or `tab_width`) in this file; those should be specified in a (personal) parent .editorconfig file outside of the repository.
# From editorconfig.org: "when `indent_style` is set to `tab`, it may be desirable to leave `indent_size` unspecified so readers may view the file using their preferred indentation width".
