+# colorize
+
+With this plugin you can syntax-highlight file contents of over 300 supported languages and other text formats.
+
+To use it, add colorize to the plugins array of your zshrc file:
+```
+plugins=(... colorize)
+```
+
+## Usage
+
+* `ccat <file> [files]`: colorize the contents of the file (or files, if more than one are provided). If no arguments are passed it will colorize the standard input or stdin.
+
+Colorize will highlight the content based on the filename extension. If it can't find a syntax-highlighting method for a given extension, it will try to find one by looking at the file contents. If no highlight method is found it will just cat the file normally, without syntax highlighting.
+
+## Requirements
+
+You have to install Pygments first: [pygments.org](http://pygments.org/download/)
