 The first item `CSharp` corresponds to the name of the language as defined in tokei. The second item `csharp.ascii` is the name of the file containing the ascii logo, this file has to be placed in the _./resources_ folder (more info below). The third item `C#` is the display name. Then we have the colors used to customize the look of the ascii logo when displayed to the screen. The last item `c#` is required only if the Enum name  `CSharp` doesn't match the display name `C#`.
 
@@ -89,13 +89,17 @@ Remarks:
  - Your ascii logo's dimensions must fall below `25*45` (height\*width). The CI will fail otherwise.
  - You can use `{N}` to color the ascii which will utilize the vec! of colors defined in `define_language!`
  - Make sure to trim any unnecessary trailing whitespaces
- - Make sure if you use true_colors that the number of true_colors matches the number of basic_colors
  - See example here [Ascii Art From Image File Using Python Image Library](https://github.com/o2sh/onefetch/wiki/ASCII-Art-From-Image-Using-Python-Image-Library)

- - These are all equal color schemes, notice that a shortcut to duplicate the basic colors is to leave out true_colors entirely:
-  ```{ CSharp, "csharp.ascii", "C#", { Colors { basic_colors: vec![Color::Blue, Color::Magenta], true_colors: Some(vec![Color::TrueColor{ r:0, g:0, b:255 }, Color::TrueColor{ r:255, g:0, b:255 }]) } }, "c#" },```
-  ```{ CSharp, "csharp.ascii", "C#", { Colors { basic_colors: vec![Color::Blue, Color::Magenta], true_colors: None } }, "c#" },```
-  ```{ CSharp, "csharp.ascii", "C#", { vec![Color::Blue, Color::Magenta] }, "c#" },```
+ - You must always provide an array of basic colors
+ - Optionally, you may provide true colors in a second array of colors separated from the first array by a colon
+ - One last approach allows you to define colors using the Colors structure itself
+ - Make sure if you use true colors that the number of true colors matches the number of basic colors
+ - For example, the following are equivalent:
+```
+    { CSharp, "csharp.ascii", "C#", define_colors!( [Color::Blue, Color::Magenta] ), "c#" },
+    { CSharp, "csharp.ascii", "C#", define_colors!( [Color::Blue, Color::Magenta] : [Color::TrueColor{ r:0, g:255, b:255 }, Color::TrueColor{ r:255, g:0, b:255 } ] ), "c#" },
