+
+| Script | Purpose | Status |
+|--------|---------|--------|
+| [onboarding.sh](onboarding.sh) | Bootstrap Ansible control node for Proxmox management | 🟡 **DRAFT** - Testing Required |
+
+---
+
+## onboarding.sh
+
+**Purpose:** Automated setup of Ansible control node for Proxmox infrastructure management.
+
+**What it does:**
+1. Installs Ansible and Proxmoxer Python library
+2. Detects or generates SSH keypair (ED25519 preferred, RSA fallback)
+3. Copies public key to Proxmox server for passwordless authentication
+4. Generates Ansible inventory file (`hosts.ini`) with Proxmox connection details
+
+**Prerequisites:**
+- Debian/Ubuntu-based system (uses `apt`)
+- Network access to Proxmox server
+- Initial SSH password for target Proxmox server
+
+**Configuration:**
+Edit the following variables at the top of the script:
+```bash
+PROXMOX_IP="192.168.1.100"       # Target Proxmox server IP
+PROXMOX_USER="root"              # Proxmox SSH user
+```
+
+**Usage:**
+```bash
+cd ~/dev/homelab/scripts
+chmod +x onboarding.sh
+./onboarding.sh
+```
+
+**Verification:**
+```bash
+ansible proxmox_nodes -m ping -i hosts.ini
+```
+
+---
+
+## ⚠️ Development Status
+
+| Script | Testing Status | Known Issues |
+|--------|---------------|--------------|
+| onboarding.sh | ❌ Untested in production | • Hardcoded Proxmox IP/user variables<br>• No error handling for failed SSH key copy<br>• Assumes Debian/Ubuntu package manager<br>• No validation of Proxmox connectivity |
+
+**DO NOT USE IN PRODUCTION** until the following are addressed:
+
+1. **Error Handling:** Add validation checks for each step
+2. **Idempotency:** Verify script can be safely re-run
+3. **Multi-OS Support:** Test on RHEL/Arch variants or add OS detection
+4. **Interactive Mode:** Prompt for PROXMOX_IP/USER instead of manual editing
+5. **Rollback:** Add cleanup mechanism for failed installations
+
+---
+
+## Contributing
+
+When adding new scripts:
+1. Update the **Inventory** table with script name and purpose
+2. Document prerequisites, configuration, and usage
+3. Mark status as 🟡 DRAFT until production-tested
+4. Add to **Development Status** table with known issues
