+
+### 4. Development Workflow
+
+With mise and hk installed, you have access to streamlined development commands:
+
+```bash
+# Development tasks
+mise run build         # Build the project
+mise run test          # Run tests
+mise run lint          # Run clippy

+## 🔧 Development Tools Overview
+
+This project uses modern development tools to streamline the contribution process:
+
+### Mise - Task Runner & Tool Manager
+
+[Mise](https://mise.jdx.dev/) manages our development environment and provides consistent task execution:
+
+```bash
+# Available tasks
+mise run build         # Build the project (alias: mise run b)
+mise run test          # Run the test suite
+mise run lint          # Run clippy linting
+mise run ci            # Full CI pipeline (build + lint + test)
+mise run clean         # Clean build artifacts
+mise run release       # Cut a new release (maintainers only)
+```
+
+### hk - Git Hooks Manager
+
+[hk](https://github.com/jdx/hk) provides automated git hooks for code quality:
+
+```bash
+# Hook commands
+hk pre-commit          # Run pre-commit checks
+hk pre-push            # Run pre-push checks  
+hk check               # Run all linters
+hk fix                 # Auto-fix issues where possible
+hk test                # Run tests only
+hk ci                  # Run CI checks
 ```
 
+### Automated Quality Checks
+
+The pre-commit hooks automatically run these tools on every commit:
+
+- **cargo fmt** - Formats Rust code
+- **cargo clippy** - Lints Rust code for common issues
+- **cargo test** - Runs the test suite (with nextest for parallel execution)
+- **typos** - Checks for spelling errors in code and documentation
+- **prettier** - Formats TOML, YAML, and other configuration files
+- **cargo deny** - Audits dependencies for security vulnerabilities and license compliance
+- **pkl** - Validates pkl configuration files
+
+### Tool Integration
+
+Both tools work together seamlessly:
+- **mise** handles tool installation and version management
+- **hk** uses the tools installed by mise for git hooks
+- Both can run the same underlying commands (e.g., `mise run test` and `hk test`)
+- CI uses the same tools for consistency between local and remote environments

 # Clone the repository
 git clone https://github.com/bashandbone/submod.git
 cd submod
 
+# Install mise if you haven't already
+curl https://mise.run | sh

+# Build the project
+mise run build
+# or: mise run b (alias)

+
+# Run the full CI suite (build + lint + test)
+mise run ci

+
+### Available Mise Tasks

+
+### Git Hooks with hk
+
+This project uses [hk](https://github.com/jdx/hk) for automated git hooks that ensure code quality:
+
+```bash
+# Install git hooks (done automatically with mise install)
+hk install
+
+# Run pre-commit checks manually
+hk pre-commit
+
+# Run all linters and checks
+hk check
+
+# Auto-fix issues where possible
+hk fix
+
+# Run CI checks locally
+hk ci
+```
+
+The pre-commit hooks automatically run:
+- **cargo fmt** - Code formatting
+- **cargo clippy** - Linting
+- **cargo test** - Test suite
+- **typos** - Spell checking
+- **prettier** - TOML/YAML formatting
+- **cargo deny** - Security and license auditing

 ### Development Guidelines
 
 - Follow Rust best practices and idioms
 - Add tests for new functionality. I'm not big on unit tests, but integration tests are essential.
 - Update documentation for user-facing changes
 - Use conventional commit messages
-- Ensure all tests pass before submitting PR
+- Run `mise run ci` or `hk ci` before submitting PR
+- Pre-commit hooks will automatically format code and run basic checks
+- All automated checks must pass before PR can be merged
