Proposed Changes

I propose to fix a spelling error in the readme file.

Types of changes

What types of changes does your code introduce to MiniScaffold?

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Correction in documentation

Checklist

• Build and tests pass locally
• I have added tests that prove my fix is effective or that my feature works (if appropriate)
• I have added necessary documentation (if appropriate)

Further comments

I find these questionnaires intimidating.
