+
+## Installation
+
+    gem install rumoji
+
+Note that rumoji has only been tested in Ruby 1.9!!!
+
+### Some examples:
+
+    puts Rumoji.encode("Lack of cross-device emoji support makes me 😭")
+
+    #=> Lack of cross-device emoji support makes me :sob:
+
+Here's a fun file:
+
+    Rumoji.decode_io($stdin, $stdout)
+
+On the command line
+
+    echo "But Rumoji makes encoding issues a :joy:" | ruby ./funfile.rb
+    #=> But Rumoji makes encoding issues a 😂
+
+Implement the emoji codes from emoji-cheat-sheet.com using a tool like [gemoji](https://github.com/github/gemoji) along with Rumoji, and you'll easily be able to transform user input with raw emoji utf-8 into images you can show to all users.
+
+_Having trouble discerning what's happening in this README?_ You might be on a device with NO emoji support! All the more reason to use Rumoji. Transcode the raw utf-8 into something users can understand across devices!
+
 Thanks!
 Thanks!
