 ScaffoldForge is a CLI tool that parses GitHub issues and automatically generates project scaffolds with starter code, file structures, and TODO comments. Developers can point it at a repo and issue, and it creates a development-ready starting point with placeholders for implementation.
 
-## Features
-
-- Parse GitHub issue descriptions, checklists, and comments
-- Generate project structures from templates
-- Create starter files with TODO comments
-- Support multiple languages (Python, JavaScript, Go, Rust)
-- Custom template system
-- Preview mode before generating
-- Interactive mode with prompts

 ## How It Works
 
-1. **Issue Parsing**: Fetches the GitHub issue and parses title, description, checklist items, and labels
+1. **Issue Parsing**: ScaffoldForge fetches the GitHub issue and parses:
-2. **Language Detection**: Automatically detects programming language from labels or content
+   - Title and description
-3. **Template Selection**: Selects appropriate templates based on language
+   - Checklist items (converted to TODO comments)
-4. **Context Generation**: Creates template context with issue data
+   - Labels (used for language detection)
-5. **File Generation**: Renders templates and writes files
+   - Requirements sections
-6. **Documentation**: Generates README.md and .gitignore
+   - Suggested file/directory paths
+
+2. **Template Selection**: Based on the detected or specified language, appropriate templates are selected.
+
+3. **Context Generation**: A template context is created with issue data and project name.
+
+4. **File Generation**: Templates are rendered with the context and files are written to the output directory.
+
+5. **Documentation**: A `README.md` and `.gitignore` are automatically generated.
+
+## Error Handling
+
+ScaffoldForge handles common errors gracefully:
+
+- **GitHub API rate limit**: Suggests using a token
+- **Invalid URL**: Validates and provides clear error messages
+- **Template errors**: Shows syntax errors in templates
+- **Permission errors**: Validates output paths
