+# /git-config - Configure git-flow
+
+## Purpose
+
+Configure git-flow settings for the current project.
+
+## Behavior
+
+### Interactive Configuration
+
+```
+git-flow Configuration
+═══════════════════════════════════════════
+
+Current settings:
+  GIT_WORKFLOW_STYLE: feature-branch
+  GIT_DEFAULT_BASE: development
+  GIT_AUTO_DELETE_MERGED: true
+  GIT_AUTO_PUSH: false
+
+What would you like to configure?
+1. Workflow style
+2. Default base branch
+3. Auto-delete merged branches
+4. Auto-push after commit
+5. Protected branches
+6. View all settings
+7. Reset to defaults
+```
+
+### Setting: Workflow Style
+
+```
+Choose your workflow style:
+
+1. simple
+   - Direct commits to development
+   - No feature branches required
+   - Good for solo projects
+
+2. feature-branch (Recommended)
+   - Feature branches from development
+   - Merge when complete
+   - Good for small teams
+
+3. pr-required
+   - Feature branches from development
+   - Requires PR for merge
+   - Good for code review workflows
+
+4. trunk-based
+   - Short-lived branches
+   - Frequent integration
+   - Good for CI/CD heavy workflows
+```
+
+### Setting: Protected Branches
+
+```
+Protected branches (comma-separated):
+Current: main, master, development, staging, production
+
+These branches will:
+- Never be auto-deleted
+- Require confirmation before direct commits
+- Warn before force push
+```
+
