+# CLI Reference
+
+Memori CLI is automatically available after `pip install memorisdk`.
+
+## Quick Reference
+
+| Command | Purpose |
+|---------|---------|
+| `memori --version` | Show version |
+| `memori init` | Create `memori.json` config |
+| `memori init --force` | Overwrite config |
+| `memori health` | Validate setup |
+| `memori health --check-db` | Check database connection |
+| `memori health --config <path>` | Validate custom config |
+
+---
+
+## Commands
+
+### `memori --version`
+
+Display installed version:
+```bash
+memori --version
+# Output: memori version 2.3.0
+```
+
+### `memori init`
+
+Create a starter configuration with sensible defaults:
+```bash
+memori init
+memori init --force    # Overwrite existing config
+```
+
+Creates `memori.json` with:
+- SQLite database connection
+- OpenAI API key placeholder
+- Memory namespace and retention policy
+- Logging configuration
+
+See [Configuration Guide](../configuration/settings.md) for detailed structure.
+
+### `memori health`
+
+Validate environment, dependencies, and configuration:
+```bash
+memori health
+memori health --config custom.json  # Validate custom config
+memori health --check-db             # Include database test
+```
+
+**Checks performed:**
+1. Package import
+2. Core dependencies (Pydantic, SQLAlchemy, OpenAI, LiteLLM, Loguru, python-dotenv)
+3. Configuration file validity and required sections
+4. Database connectivity (with `--check-db`)
+
+**Exit codes:**
+- `0`: All checks passed
+- Non-zero: At least one check failed
+
+---
+
+## Workflow
+
+```bash
+# 1. Create config
+memori init
+
+# 2. Edit memori.json
+# Set your OpenAI API key and adjust settings as needed
+
+# 3. Validate setup
+memori health --check-db
+
+# 4. Use in Python
+python your_script.py
+```
+
+## CI/CD Integration
+
+```yaml
+# .github/workflows/test.yml
+- name: Install dependencies
+  run: pip install memorisdk
+
+- name: Verify memori setup
+  run: memori health --check-db
+```
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| Command not found | `pip install memorisdk` |
+| Config not found | `memori init` |
+| Invalid JSON | `memori init --force` |
+| Missing dependencies | `pip install memorisdk[all]` |
+| Database connection error | Check `connection_string` in `memori.json` |
