+
+## 🔧 Installation
+
+### New Installations
+
+For new Proxmox VE 9 systems without existing freenas-proxmox plugin:
+
+```bash
+# Download the installer
+wget https://raw.githubusercontent.com/TheGrandWazoo/freenas-proxmox/pve9-support/install-pve9.sh
+
+# Make executable and run
+chmod +x install-pve9.sh
+sudo ./install-pve9.sh
+```
+
+### Existing Installations
+
+For Proxmox VE 9 systems with existing freenas-proxmox plugin that needs PVE 9 fixes:
+
+```bash
+# Download the patcher
+wget https://raw.githubusercontent.com/TheGrandWazoo/freenas-proxmox/pve9-support/patch-pve9.sh
+
+# Make executable and run  
+chmod +x patch-pve9.sh
+sudo ./patch-pve9.sh
+```
+
+## ⚙️ Configuration
+
+### 1. SSH Key Setup
+
+Configure SSH key authentication between Proxmox and TrueNAS:
+
+```bash
+# Create SSH key directory
+mkdir -p /etc/pve/priv/zfs
+
+# Generate SSH key (replace TRUENAS_IP with your TrueNAS IP)
+ssh-keygen -f /etc/pve/priv/zfs/TRUENAS_IP_id_rsa
+
+# Copy public key to TrueNAS
+ssh-copy-id -i /etc/pve/priv/zfs/TRUENAS_IP_id_rsa.pub root@TRUENAS_IP
+
+# Test connectivity
+ssh -i /etc/pve/priv/zfs/TRUENAS_IP_id_rsa root@TRUENAS_IP "midclt call system.info"
+```
+
+### 2. TrueNAS iSCSI Configuration
+
+Ensure your TrueNAS system has:
+- **iSCSI service enabled**
+- **Portal configured** with appropriate network settings
+- **Target created** for Proxmox access
+- **Authentication configured** (CHAP recommended)
+
+### 3. Proxmox Storage Configuration
+
+Add FreeNAS storage through the Proxmox web interface:
+
+1. Navigate to **Datacenter → Storage → Add**
+2. Select **"ZFS over iSCSI"** as storage type
+3. Configure the following:
+   - **ID**: `freenas-storage` (or your preferred name)
+   - **Portal**: Your TrueNAS IP address
+   - **Target**: Your TrueNAS iSCSI target IQN
+   - **Pool**: ZFS pool name on TrueNAS
+   - **Block size**: `8k` (recommended)
+   - **iSCSI provider**: `freenas`
+   - **FreeNAS API host**: Your TrueNAS IP address  
+   - **FreeNAS user**: `root`
+   - **FreeNAS password**: Your TrueNAS root password
+   - **Content**: Select `Disk image` and `Container` as needed
+
+## 🐛 Critical Fixes Applied
+
+### LUN 0 Handling Fix
+
+**Problem**: Proxmox VE 9 had a critical bug where LUN 0 was treated as a falsy value, causing VM startup failures.
+
+**Solution**: Fixed the condition check from `if !$guid` to `if !defined $guid` in ZFSPlugin.pm.
+
+**Impact**: VMs with disks on LUN 0 can now start successfully.
+
+### Return Format Compatibility
+
+**Problem**: Function return formats between `list_lu` and `zfs_get_lun_number` were incompatible.
+
+**Solution**: Standardized return formats to ensure proper data flow between functions.
+
+**Impact**: Eliminates "unknown method" and parsing errors.
+
+### Complete Method Implementation
+
+**Problem**: Missing or incomplete LUN command methods in FreeNAS.pm.
+
+**Solution**: Implemented all required methods with proper error handling.
+
+**Impact**: Full iSCSI LUN management functionality.
+
+## 🧪 Testing
+
+After installation, test the integration:
+
+### 1. Verify Storage Recognition
+
+```bash
+# Check storage status
+pvesm status
+
+# List available storage
+pvesm list freenas-storage
+```
+
+### 2. Create Test VM
+
+1. Create a new VM through Proxmox web interface
+2. Select your FreeNAS storage for the disk
+3. Start the VM and verify it boots correctly
+
+### 3. Test Cloud-init Support
+
+Create a VM with cloud-init enabled and verify the cloud-init disk is properly created on TrueNAS storage.
+
+## 🔍 Troubleshooting
+
+### Common Issues
+
+**VM fails to start with "Could not find lu_name" error:**
+- Ensure the patcher was applied correctly
+- Check that FreeNAS storage is properly configured
+- Verify SSH connectivity to TrueNAS
+
+**iSCSI connection failures:**
+- Verify TrueNAS iSCSI service is running
+- Check network connectivity between Proxmox and TrueNAS
+- Ensure proper authentication configuration
+
+**Storage not appearing in Proxmox:**
+- Verify ZFSPlugin.pm includes freenas provider support
+- Check Proxmox service status: `systemctl status pvedaemon`
+- Review logs: `/var/log/daemon.log`
+
+### Debug Mode
+
+To enable detailed debug logging:
+
+```bash
+# Enable debug logging
+export PVE_DEBUG_STORAGE=1
+
+# Restart pvedaemon
+systemctl restart pvedaemon
+
+# Check logs
+tail -f /var/log/daemon.log | grep -i freenas
+```
