 ## Features
 
+### GitHub Analysis
 - **Commit Analysis** - Track commits with detailed statistics including additions, deletions, merge detection, and revert identification
 - **Pull Request Metrics** - Monitor PR workflow, merge times, review coverage, and approval rates
 - **Issue Tracking** - Analyze issue resolution times, categorization (bugs vs enhancements), and closure rates
 - **Contributor Insights** - Identify top contributors with activity metrics and productivity scoring
 - **Multi-Repository Support** - Analyze multiple repositories in a single run with aggregated statistics
 - **Quality Metrics** - Assess code quality through revert ratios, review coverage, and commit message analysis
 - **Productivity Scoring** - Calculate composite productivity scores for contributors across repositories
+
+### Jira Integration (NEW)
+- **Jira Issue Extraction** - Extract issues and comments from Jira Cloud and Server/Data Center
+- **Multi-Project Support** - Analyze multiple Jira projects with interactive project selection
+- **Time-Based Filtering** - Filter issues by update date using JQL queries
+- **Comment Tracking** - Export all issue comments with author and timestamp
+- **ADF Support** - Automatically converts Atlassian Document Format to plain text
+
+### Core Features
+- **Multi-Source CLI** - Use `--sources` flag to select GitHub, Jira, or both
+- **Auto-Detection** - Automatically detects available sources from environment credentials
 - **Zero Dependencies** - Works with Python standard library only (optional `requests` for better performance)
-- **Secure Token Handling** - Token loaded from environment variable, never exposed in logs or error messages
