 In Illustrator, it's [a little different](http://f.cl.ly/items/071J0Q2m0D38250g2s1F/shields_resize_illustrator.mov) (4.8 MB .mov video).
 
+
+## Installation (ruby class / command line)
+
+[![Build Status](https://travis-ci.org/OriPekelman/shields.io.png?branch=gemify)](https://travis-ci.org/OriPekelman/shields.io)
+
+There is a small ruby class / command line tool to generate the images from a template. 
+It can output a parametrized SVG, or any format (gif/png/jpg) etc..
+
+Add this line to your application's Gemfile:
+
+    gem 'shields_io'
+
+And then execute:
+
+    $ bundle
+
+Or install it yourself as:
+
+    $ gem install shields_io
+
+## Command line Usage
+
+    Usage: ./generate_shield [options]
+
+        example:
+        ./generate_shield --height=18 --vendor_text=Travis --vendor_width=40 --vendor_color=gray --status_text=Passing --status_color=green --format=png >travis.png
+
+        -v,                     Print the version
+            --font_size         Font size
+            --height            Shield height
+            --vendor_text       Vendor text
+            --vendor_width      Vendor width
+            --vendor_color      Vendor Color gray,lightgray,darkgray,green,yellowgreen,yellow,red
+            --status_text       Status Text
+            --status_width      Status Width
+            --status_color      Status Color gray,lightgray,darkgray,green,yellowgreen,yellow,red
+            --format            Format svg, png etc..
+        -h, --help              Display this help message.
+
+
+## Use in code (ruby)
+    require "shields_io"
+    ShieldsIo::SVG.new(opts).render # will render an svg opts is a hash of options
+    ShieldsIo::SVG.new(opts).render_bitmap "gif" # will render a gif (default bitmap format is png) opts is a hash of options
