 ## How to run demos
 
+The `demo_ppm` program demonstrates various operations on PPM (Portable Pixmap) images. It generates Mandelbrot fractals, performs diverse manipulations, and exports images in the PPM format.
+
+The `demo_color` program showcases manipulation of color spaces and their conversions. This program sets a custom color using various methods, converts it to different color spaces, retrieves color values, finds the nearest color, and prints color details.
