+# Python Caeser Cipher Helper
+
+# What's That?
+
+This script gives you tools to manipulate text with the Caeser Cipher.
+It'll take any input you give it, filter it and process it as you want (encrypt or decrypt) and will attempt to crack it if you don't know the shift.
+
+This is a fun tool, not security. The Caeser Cipher was broken in A.D. 800 (or earlier) for longer messages unless you use a one time pad and a randomly generated shift. But, it's fun to break and manipulate.
+
+This tool is a work in progress.
+
+# Requirements
+
+  Python `=>` 3.5.2
+
+# Usage
+
+### Encrypt
+
+`python3 caeser-cipher.py encrypt "secretmessage"`
+
+For example: `python3 caeser-cipher.py encrypt "Hi, how are you?""`
+
+### Decrypt
+
+`python3 caeser-cipher.py decrypt "encryptedtext"`
+
+For example: `python3 caeser-cipher.py decrypt "hhhhhhhhhh"`
