 ### Basic Workflow
 
 1. **Select an Icon**
-   - Click "Choose Icon" to open the icon picker
+   - Click on one of the preset framework icons (React, Angular, Vue, Python, etc.)
+   - Or click the "+" button to open the full icon picker
    - Search for icons by name (e.g., "github", "twitter", "gaming")
    - Click an icon to select it
 
 2. **Customize the Gradient**
-   - Choose between Linear or Radial gradient types
-   - Drag color stops on the gradient bar to reposition them
-   - Click stops to change their colors
-   - Add or remove stops using the buttons
-   - Apply preset gradient styles (Smooth, Glossy, Vibrant, Subtle)
+   - **Choose Base Color**: Select a base color using the color picker
+   - **Apply Preset Style**: Click Smooth, Glossy, Vibrant, or Subtle to generate a gradient based on your base color
+   - **Switch Gradient Type**: Toggle between Linear and Radial gradients
+   - **Adjust Angle**: For linear gradients, drag the angle slider (0-360°)
+   - **Modify Color Stops**:
+     - Click on a stop indicator to make it active
+     - Use the color picker to change the active stop's color
+     - Drag the position slider to reposition the stop (0-100%)
+     - Click "+" to add a new stop
+     - Click "−" to remove the active stop (minimum 2 stops required)
+   - **Toggle Color Mode**: Switch between RGB and HSL modes
+   - **Randomize**: Click "Randomize" for instant random gradients
 
 3. **Adjust Icon Settings**
-   - Set icon color using the color picker
-   - Adjust icon size (20-80%)
-   - Fine-tune vertical offset (-30% to +30%)
+   - Set icon color using the color picker (default: white)
+   - Adjust icon size using the slider (20-80%)

 ### Gradient Randomizer
 
 1. **Basic Randomization:**
-   - Click "Randomize Gradient" to generate a random gradient
-
-2. **Color-Based Randomization:**
-   - Select a base color in the "Random base color" picker
-   - Click "Randomize Gradient" to generate variations based on that color
-   - For grayscale base colors (low saturation), generates grayscale gradients
-   - For colorful base colors, generates same-hue gradients with varying lightness
-
-3. **Clear Base Color:**
-   - Click the "×" button to return to fully random gradients
+   - Click "Randomize" button to generate a completely random gradient
+   - Random type (linear or radial), angle, number of stops, and colors
+
+2. **Base Color Gradients:**
+   - Select a base color using the "Base Color" picker
+   - Click a preset style button (Smooth, Glossy, Vibrant, or Subtle)
+   - For grayscale colors (black, white, gray), generates smooth grayscale gradients
+   - For vibrant colors, generates same-hue gradients with varying lightness and saturation
+   - **Smooth**: 2-stop simple gradients
+   - **Glossy**: 3-4 stops with highlights for a glossy effect
+   - **Vibrant**: High saturation color bursts
+   - **Subtle**: Low saturation, gentle transitions
+
+3. **Manual Control:**
+   - Click any gradient stop indicator to select it
+   - Use the visible color picker to change the stop color to any value
+   - Drag the position slider or the stop itself on the gradient bar
+   - Add or remove stops as needed for complete control
