 # Ciphers
 A program to help with some simple ciphers
+This program is designed to allow you to play with some simple ciphers, like the Caesar Cipher.
+Because of how simple these ciphers are they will likely not be of any use if you actually want to keep your data safe
+
+#Caesar Cipher
+This cipher is very easy to learn and simple to encode or decode.
+It just shifts the letters a certain number of spaces, i.e. for a shift of 3 a=d & x=a
+
+#Playfair Cipher
+This cipher is a little more complex.
+It uses a key to create a grid of letters that is then used to encode 2 letters at a time. It is a simple form of 16-bit encryption.
+It is still fairly simple to learn to do by hand, just time consuming if it is a long message or if you are trying to crack the key.
