+## Download Binary
+
+If you want to download the statically linked binary, fetch the latest release
+from https://git.stefan.works/whx/based/releases .
+
+## Usage
+
+* Pipe via stdin to transcode
+* Modes are __encode__ and __decode__
+* Encoding is done in the following way
+```sh
+echo Hello, World! | based encode --b91
+>OwJh>}AQ;r@@Y?FF

+* Decoding is implicated in the following way 
+```sh
+echo '>OwJh>}AQ;r@@Y?FF' | based --b91

+### Tests
+
+Run `cabal test`
+
+## What is Transcoded?
+
+The following are the supported encodings
+
+* Base91 
+* Base85 
+* Base64
+* Base64url 
+* URL Encoding 
+* Base62 
+* Base58 
+* Base45
+* Base32 
+* Base16
+* Base10
+* Base2
+* Quoted-Printable
+* UU Encoding
+* XX Encoding
+* yEncoding
+* Rotate (1..26)
