A Roman numeral is a sequence of these letters, and its value is the sum of the letters' values.
For example, `XVIII` has the value 18 (`10 + 5 + 1 + 1 + 1 = 18`).

There's one rule that makes things trickier though, and that's that **the same letter cannot be used more than three times in succession**.

Entirely a modern invention but not worth updating the docs upstream. There are plenty of examples in classical times where this wasn’t true.

Nah. If we touch it here, configlet will think our docs are out of date and flag it for a resync. We can add additional content via instructions or introductions append files that get appended to the end of the appropriate file. That’s more intended for track specific content though.
