Basic Editor Settings - Tabs and Spaces

Use TABs rather than Spaces

Using TABS can eliminate many unnecessary code merges.

By using TABs, each developer can adjust their IDE to however many spaces of indentation they prefer.  One TAB = one scope of logic, whether it be the main block, an additional indention for a while loop, etc.  This keeps everyone's code consistent and accommodating for each person's indentation preferences.

Consider configuring a git hook to automatically applying this formatting rule before pushing any code to your remote repository.
