 # Let's make a colorful world!
+# What's this?
+We often use ASCII color like `\033[0m` when developing. But it's hard to remember them.          
+When writing shell, we can use `CLEAR='\033[0m'`, but for C, I have to write the implementation myself.       
+So I use `{color}` for text color and `[color]` for background color, and make them map to print the color, that's this project. Simple, stupid, maybe a bit useless.
+I use it to format output in my program.        
+# About the binary:
+You can just use cprintf as a modified version of "echo -ne" with the color format support. If the color in `{}` or `[]` is not recognized, it will just output the original string.        
 # Note:
 `cprintf()` and `cfprintf()` is a macro and will not return anything.       
 # Cprintf in production:
