 # ClassicalCiphers
 
+## Main Features
+
+Provides access to encryption and decryption of strings according to a variety of classical algorithms.
+The Solitaire cipher is included for completeness, though it is perhaps not strictly classical.
+
+## Currently Implemented
+
+* [Caesar]
+* [Monoalphabetic substitution]
+* [Vigenère]
+* [Solitaire]
+
