	# What the execution context is:
	# The creation of a pull request. Can also be triggered manually.

	# What it does:
	# Performs Markdown linting on the content of the pull request.

	# Why we need it:
	# To maintain a level of consistency in the markup content.

	# What's important to know:
	# As well as the rules defined in the configuration, a custom
	# rule is also employed to check title case.
