-## Styles
+## Configuration
 
-Pygments offers multiple styles. By default, the `default` style is used, but you can choose another theme by setting the `ZSH_COLORIZE_STYLE` environment variable:
+### Requirements
 
-`ZSH_COLORIZE_STYLE="colorful"`
+This plugin requires that at least one of the following tools is installed:
 
-## Usage
+* [Chroma](https://github.com/alecthomas/chroma)
+* [Pygments](https://pygments.org/download/)
 
-* `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 tool
 
-* `cless <file> [files]`: colorize the contents of the file (or files, if more than one are provided) and
-  open less. If no arguments are passed it will colorize the standard input or stdin.
+Colorize supports `pygmentize` and `chroma` as syntax highlighter. By default colorize uses `pygmentize` unless it's not installed and `chroma` is. This can be overridden by the `ZSH_COLORIZE_TOOL` environment variable:
 
-Note that `cless` will behave as less when provided more than one file: you have to navigate files with
-the commands `:n` for next and `:p` for previous. The downside is that less options are not supported.
-But you can circumvent this by either using the LESS environment variable, or by running `ccat file1 file2|less --opts`.
-In the latter form, the file contents will be concatenated and presented by less as a single file.
