.editorconfig

Here's the editor config that I typically use. Yes, I'm choosing spaces, but hey, if you prefer tabs, we can still be friends, I guess...

Unless you start preaching to me.

Config Setup

root = true

[*]
indent_style = space
indent_size = 4
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true

[*.md]
trim_trailing_whitespace = false

Ollie enforces a four-space indentation (tab) style, the end-of-line should use a line feed, and we will be trimming white space and inserting a final newline automatically with the provided .editorconfig.
