+# Dancing Sine Wave Animation
+
+A simple Python program using `pygame` to create a **moving sine wave with dancing dots**. The dots follow a sine wave and exhibit subtle random vertical movements, giving a lively "dancing" effect.
+
+## Features
+
+- Animated sine wave with moving dots.
+- Dots have slight vertical offsets for a dancing effect.
+- Adjustable parameters: amplitude, frequency, speed, number of dots, colors.
+- Smooth 60 FPS animation.
+
+## How It Works
+
+1. Dots are evenly spaced along the x-axis of the screen.
+2. Y-position of each dot is calculated using a sine function with a time-based offset for horizontal motion.
+3. Random vertical offsets are added to each dot for the dancing effect.
+4. `pygame` renders the dots on a dark background.
+
+## Parameters
+
+- `AMPLITUDE` – wave height.  
+- `FREQUENCY` – number of waves across the screen.  
+- `SPEED` – horizontal movement speed.  
+- `NUM_DOTS` – number of dots along the wave.  
+- `DOT_RADIUS` – size of each dot.  
+- `BG_COLOR` and `DOT_COLOR` – customize colors.
+
+## Requirements
+
+- Python 3.6+  
+- `pygame` (`pip install pygame`)
