 # Img2ColorfulChars
 Load image and print colorful chars in C# console.
+
+### Usage
+1. Build this project or use Img2ColorfulChars.exe in _Output.
+2. Run command ```Img2ColorfulChars.exe ImagePath Scale``` and enjoy your colorful chars.  
+eg. 
+``` cmd
+cd _Output
+Img2ColorfulChars.exe np.png 4
+``` 
+> Notice: Scale should be positive integar, and larger scale gets smaller image.  
+
