+# Setup Wizard CLI
+
+## Module
+Cli
+
+## Status
+IMPLEMENTED
+
+## Description
+Interactive setup wizard with checkpoint-based state management: run full or specific steps, resume from interruption, check status, reset state, and validate configuration. Supports YAML config files and non-interactive mode.
+
+## Implementation Details
+- **Command Group**: `src/Cli/StellaOps.Cli/Commands/Setup/` -- setup wizard commands
+- **Prompts**: `src/Cli/StellaOps.Cli/Prompts/` -- interactive prompt infrastructure
+- **Commands**:
+  - `stella setup` -- run full setup wizard interactively
+  - `stella setup run --step <name>` -- run a specific setup step
+  - `stella setup status` -- check setup completion status
+  - `stella setup resume` -- resume from last checkpoint
+  - `stella setup reset` -- reset setup state
+  - `stella setup validate` -- validate current configuration
+- **Non-interactive**: `--config <yaml>` for automated setup
+
+## E2E Test Plan
+- [ ] Run `stella setup` and verify interactive wizard prompts
+- [ ] Run `stella setup run --step database` and verify specific step execution
+- [ ] Run `stella setup status` and verify step completion status
+- [ ] Interrupt setup and run `stella setup resume` and verify resumption from checkpoint
+- [ ] Run `stella setup reset` and verify state cleared
+- [ ] Run `stella setup validate` and verify configuration validation
+- [ ] Run with `--config ./setup.yaml` for non-interactive mode
