 # SnapSort  
 
-### Note: SnapSort is currently in development and may not be fully functional.
-
 **SnapSort** is a light weighted (relatively) command-line tool that helps you classify and organize your photos based on focus accuracy, exposure (overexposed/underexposed), and content (landscape/portrait). SnapSort leverages OpenCV for image processing and allows you to quickly sort your photos into categorized folders for easy management.
 
 ## Features
 - **Semantic search**: Search for images based on your prompt.
-- **Exposure Classification**: Identify overexposed and underexposed images.
 - **Find similar images**: Find similar images based on a reference image.
+- **Exposure Classification**: Identify overexposed and underexposed images.
 
 ## Installation

+# SnapsSort CLI Usage Examples
+
+## Semantic Search
+
+Find images based on a text description:
+
+```bash
+# Search for images containing animals
+snapsort search animals
+# Search for images containing cars and people
+snapsort search "car and people"
+# Search for landscape images (limit to top 5 results)
+snapsort search landscape -n 5
+```
+
+## Similar Image Discovery
+
+Find images similar to a reference image:
+
+```bash
+# Find images similar to a specific image
+snapsort similar /path/to/reference/image.jpg
+```
+
+## Exposure Classification
+
+Sort images by exposure levels:
+
+```bash
+# Retrieve images with different exposure characteristics
+snapsort tone low      # Underexposed images
+snapsort tone mid      # Balanced exposure images
+snapsort tone high     # Overexposed images
+```
+
+## Redo last command
+```bash
+# Revert the folder structure to the state before the last command
+snapsort redo
+```
+## Key Features
+
+- **Semantic Search**: Discover images using natural language descriptions
+- **Similar Image Finder**: Locate visually similar images
+- **Exposure Sorting**: Classify images by their light and tone characteristics
+
+**Note**: Ensure you're in the target directory before running these commands.
