+4. **Steps to reproduce** the issue
+5. **Expected vs actual behavior**
+
+### Suggesting Features
+
+We welcome feature suggestions! Please:
+

+3. **Propose a solution** if you have one in mind
+4. **Consider backwards compatibility** and cross-platform support
+

+
+### Coding Standards
+
+#### Shell Script Best Practices
+
+- **Bash requirement**: All scripts use Bash (use `#!/usr/bin/env bash`)
+- **Set strict mode**: Use `set -e` to exit on errors
+- **Quote variables**: Always quote variables: `"$var"`
+- **Use local variables**: Declare function-local vars with `local`
+- **Error handling**: Check return codes and provide clear error messages
+- **Target Bash 3.2+**: Code runs on Bash 3.2+ (macOS default), but Bash 4.0+ features (like globstar) are allowed where appropriate
+
+#### Code Style
+
+- **Function names**: Use `snake_case` for functions
+- **Variable names**: Use `snake_case` for variables
+- **Constants**: Use `UPPER_CASE` for constants/env vars
+- **Indentation**: 2 spaces (no tabs)
+- **Line length**: Keep lines under 100 characters when possible
+- **Comments**: Add comments for complex logic
+
+#### Example:
+
+```bash
+#!/usr/bin/env bash
+# Brief description of what this file does
+
+# Function description
+do_something() {
+  local input="$1"
+  local result
+
+  if [ -z "$input" ]; then
+    log_error "Input required"
+    return 1
+  fi
+
+  result=$(some_command "$input")
+  printf "%s" "$result"
+}
+```
+
+### Adding New Features
+
+#### Adding an Editor Adapter
+
+1. Create `adapters/editor/yourname.sh`:
+
+```bash
+#!/usr/bin/env bash
+# YourEditor adapter
+
+editor_can_open() {
+  command -v yourcommand >/dev/null 2>&1
+}
+
+editor_open() {
+  local path="$1"
+
+  if ! editor_can_open; then
+    log_error "YourEditor not found. Install from https://..."
+    return 1
+  fi
+
+  yourcommand "$path"
+}
+```
+
+2. Update README.md with setup instructions
+3. Update completions to include new editor
+4. Test on macOS, Linux, and Windows if possible
+
+#### Adding an AI Tool Adapter
+
+1. Create `adapters/ai/yourtool.sh`:
+
+```bash
+#!/usr/bin/env bash
+# YourTool AI adapter
+
+ai_can_start() {
+  command -v yourtool >/dev/null 2>&1
+}
+
+ai_start() {
+  local path="$1"
+  shift
+
+  if ! ai_can_start; then
+    log_error "YourTool not found. Install with: ..."
+    return 1
+  fi
+
+  (cd "$path" && yourtool "$@")
+}
+```
+
+2. Update README.md
+3. Update completions
+4. Add example usage
+
+#### Adding Core Features
+
+For changes to core functionality (`lib/*.sh`):
+
+1. **Discuss first**: Open an issue to discuss the change
+2. **Maintain compatibility**: Avoid breaking existing configs
+3. **Add tests**: Provide test cases or manual testing instructions
+4. **Update docs**: Update README.md and help text
+5. **Consider edge cases**: Think about error conditions
+
+### Testing
+
+Currently, testing is manual. Please test your changes on:
+
+1. **macOS** (if available)
+2. **Linux** (Ubuntu, Fedora, or Arch recommended)
+3. **Windows Git Bash** (if available)
+
+#### Manual Testing Checklist
+
+- [ ] Create worktree with branch name
+- [ ] Create worktree with branch containing slashes (e.g., feature/auth)
+- [ ] Create from remote branch
+- [ ] Create from local branch
+- [ ] Create new branch
+- [ ] Open in editor (if testing adapters)
+- [ ] Run AI tool (if testing adapters)
+- [ ] Remove worktree by branch name
+- [ ] List worktrees
+- [ ] Test configuration commands
+- [ ] Test completions (tab completion works)
+- [ ] Test `gtr go 1` for main repo
+- [ ] Test `gtr go <branch>` for worktrees
+
+### Pull Request Process
+
+1. **Fork the repository**
+2. **Create a feature branch**: `git checkout -b feature/my-feature`
+3. **Make your changes**
+4. **Test thoroughly** (see checklist above)
+5. **Update documentation** (README.md, help text, etc.)
+6. **Commit with clear messages**:

+
+## Design Principles
+
+When contributing, please keep these principles in mind:
+
+1. **Cross-platform first** - Code should work on macOS, Linux, and Windows
+2. **No external dependencies** - Avoid requiring tools beyond git and basic shell
+3. **Config over code** - Prefer configuration over hardcoding behavior
+4. **Fail safely** - Validate inputs and provide clear error messages
+5. **Stay modular** - Keep functions small and focused
+6. **User-friendly** - Prioritize good UX and clear documentation
+
+## Community
+
+- **Be respectful** and constructive
+- **Help others** who are learning
+- **Share knowledge** and best practices
+- **Have fun!** This is a community project
+
+## Questions?
+
+- Open an issue for questions
+- Check existing issues and docs first
+- Be patient - maintainers are volunteers
+
+Thank you for contributing! 🎉
