+"""Descriptions of English, used for building language models.
+
+Language models are for understanding what English looks like, for help with
+cipher breaking.
+
+* `count_1l.txt`: counts of single letters
+* `count_2l.txt`: counts of pairs letters, bigrams
+* `count_3l.txt`: counts of triples of letters, triagrams
+* `words.txt`: a dictionary of words, used for keyword-based cipher breaking.
+ These words should only contain characters cointained in
+ `string.ascii_letters`.
+
+See [`szyfrow/language_models`](../support/language_models.html) for how these files are used.
