+# XKCD Roman Numeral Encoding
+
+This is a little toy encoder that implements the encoding demonstrated in the alt-text of [XKCD 2637](https://xkcd.com/2637).
+
+I make a few opinionated changes to have the encoding be reversible, which unfortunately ruins the joke in the alt-text.
+I am considering making that a command-line option, however.
+
+It could also be fun to have the decoder spit out every possible decoding of the text input.
