+## Configuration
 
-## Styles
+### Colorize tool
+
+Colorize supports using either the `pygmentize` tool or the `chroma` tool.  By default colorize uses `pygmentize` unless it's not installed & `chroma` is installed.  However, you can override this with the `ZSH_COLORIZE_TOOL` environment variable:
+
+```
+ZSH_COLORIZE_TOOL=chroma
+```
+
+### Styles
 
 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:
 
-`ZSH_COLORIZE_STYLE="colorful"`
+```
+ZSH_COLORIZE_STYLE="colorful"
