-# Git Diff Explainer CLI
+# git-diff-explainer-cli
 
-A CLI tool that parses git diffs and provides intelligent, contextual explanations of code changes. Identifies programming language, summarizes changes, flags potential issues, and suggests improvements - all running locally without external API dependencies.
+A CLI tool that uses LLMs to explain git diffs in natural language.
 
 ## Features
 
-- Parse git diffs/patches: Extract file names, hunks, and code changes from unified diff format
-- Identify programming language: Detect language from file extensions and code patterns
-- Summarize changes: Generate human-readable summaries of what each change does
-- Flag potential issues: Detect bugs, security vulnerabilities, and code smells
-- Suggest improvements: Provide specific refactoring suggestions
-- Local execution: Runs entirely offline using local libraries
-- Color-coded output: Terminal output with ANSI colors for better readability
+- Explain git diffs using AI (OpenAI, Anthropic, or local LLMs)
+- Support for multiple diff formats (unified, side-by-side, stats)
+- Configurable explanation depth (brief, detailed, comprehensive)
+- Interactive mode for follow-up questions
+- Batch processing of multiple files
