 Dependencies
 ------------
-``tableformatter`` requires that at least one of the following two modules are installed to support table colors:
+``tableformatter`` does not have any required dependencies.
+
+However, if you wish to use the provided optional support for color, then at least one of the following two modules must be installed:
 * [colorama](https://github.com/tartley/colorama)
 * [colored](https://github.com/dslackw/colored)
 
-**pip** will treat ``colorama`` as a dependency and install if it isn't already installed.  However, if ``colored`` is
-installed, then it will be used instead of ``colorama``.
+If both ``colorama`` and ``colored`` are installed, then ``colored`` will take precedence.
