+### Graphite
+
+Graphite revolutionizes Git workflows with stacked pull requests, enabling faster reviews and parallel development by breaking large changes into manageable, interdependent PRs.
+
+Key commands:
+
+```bash
+gt branch create <feature-name>              # Create a stacked branch
+gt create --all --message "feat: <summary>"  # Stage and commit all changes
+gt submit --stack --reviewers <user1>,<user2>  # Submit entire stack with reviewers
+gt sync --restack                        # Sync and restack branches
+gt up 2                                  # Navigate up 2 branches in stack
+gt down                                  # Move down the stack
+gt stack                                 # View current stack structure
+gt repo sync                             # Sync all branches in repo
+```

 ## Features
 
-- **Pre-commit checks**: Runs pre-commit hooks on push (includes Python linting with black/flake8/mypy/bandit/safety, C++ formatting/linting with clang-format and clang-tidy, Rust formatting/linting/compilation with rustfmt/clippy, Bash linting with shellcheck, Dockerfile linting with hadolint, YAML linting with yamllint, GitHub Actions linting with actionlint, Dart linting and testing, and general checks).
-- **YAML linting**: Runs check-yaml from pre-commit.
-- **Commit message validation**: Commit-msg hook ensures messages start with conventional type and are lowercase ≤60 chars. Pre-push hook enforces stricter format with scope, ≤40 chars.
-- **Author identity verification**: Checks that commits are authored by "Niladri Das" with email "[email protected]".
-- **Automated vulnerability scanning**: CodeQL and Trivy bots scan every push and PR for security issues, ensuring robust protection.
-- **Ollama model management**: Rust tool for fetching, downloading, and running Ollama models from the internet.
-- **Testing**: Comprehensive unit tests for the Dart CLI, run automatically in CI.
-- **Version management**: Dart-powered version bump bot automates semantic versioning updates for the package.
-- **Automation workflows**: GitHub Actions for automated version bumps via PRs and release creation. See [automation documentation](./.github/workflows/automation/README.md).
+- **Code quality assurance**: Pre-commit hooks enforce linting, formatting, and testing across `Python`, `Rust`, `C++`, `Bash`, `YAML`, `Docker`, `GitHub Actions`, and `Dart`.
+- **Commit standards**: Validates conventional commit messages and author identity for consistent history.
+- **Security scanning**: Automated `CodeQL` and `Trivy` checks safeguard against vulnerabilities on every push and PR.
+- **AI model management**: `Rust`-based `Ollama` tool for seamless model fetching, downloading, and execution.
+- **Git workflow enhancement**: `Graphite` enables efficient stacked pull requests for parallel development and faster reviews.
+- **Automated testing**: Comprehensive `Dart` CLI unit tests run in CI for reliability.
+- **Version automation**: `Dart`-powered bot handles semantic versioning and release workflows via `GitHub Actions`.
