 # Nonograms
 
 Link do aplikacji: https://nonograms.7u.pl
+
+## English Description
+
+Nonograms is a modern, fast, and accessible logic puzzle game (also known as Picross or Griddlers). Solve pixel-art puzzles by marking cells according to numeric clues for rows and columns. The app features:
+- Clean UX with keyboard and touch support
+- Multiple languages and PWA support (installable on desktop and mobile)
+- Difficulty simulation and guide to learn solving strategies
+- Shareable puzzles and persistent progress
+
+Play online at https://nonograms.7u.pl or install as a PWA for an app-like experience.
