These checks take a look at your code and ensure a consistent coding style.
Using tabs or spaces? Both is fine, just don't mix them or Credo will tell
you.
""",
readability: """
Readability checks do not concern themselves with the technical correctness
of your code, but how easy it is to digest.
""",
refactor: """
The Refactor checks show you opportunities to avoid future problems and
technical debt.
""",
design: """
While refactor checks show you possible problems, these checks try to
highlight possibilities, like - potentially intended - duplicated code or
TODO and FIXME comments.
""",
warning: """
These checks warn you about things that are potentially dangerous, like a
missed call to `IEx.pry` you put in during a debugging session or a call
to String.downcase without using the result.
