+---
+
+# 🚀 OpenSign Deployment Guide on Azure VM (Frontend + Backend + MongoDB + Caddy)
+
+## 🧱 Prerequisites
+
+- Azure CLI installed
+- A domain you control (e.g., `yourdomain.com`)
+- Subdomain pointing to your VM (e.g., `opensign.yourdomain.com`)
+- SSH access
+
+---
+
+## 🔧 Step 1: Create an Azure VM
+
+### 1.1 Create Resource Group
+```bash
+az group create --name OpenSignRG --location eastus
+```
+
+### 1.2 Create Ubuntu VM
+```bash
+az vm create \
+  --resource-group OpenSignRG \
+  --name opensign-vm \
+  --image Ubuntu2404 \
+  --admin-username azureuser \
+  --generate-ssh-keys \
+  --size Standard_B1ms
+```
+
+### 1.3 Get VM IP
+```bash
+az vm list-ip-addresses --name opensign-vm --resource-group OpenSignRG --output table
+```
+
+---
+
+## 🔐 Step 2: Open Required Ports
+
+Azure’s default port-opening approach conflicts if you use the same priorities. So instead, **add rules with increasing priorities** manually:
+
+### 2.1 Get NSG name
+```bash
+az network nsg list --resource-group OpenSignRG --query "[].name"
+```
+
+Assume it’s `opensign-vmNSG`. Then:
+
+### 2.2 Add inbound port rules
+```bash
+az network nsg rule create \
+  --resource-group OpenSignRG \
+  --nsg-name opensign-vmNSG \
+  --name Allow-HTTP \
+  --priority 1001 \
+  --direction Inbound \
+  --protocol Tcp \
+  --access Allow \
+  --destination-port-ranges 80
+
+az network nsg rule create \
+  --resource-group OpenSignRG \
+  --nsg-name opensign-vmNSG \
+  --name Allow-HTTPS \
+  --priority 1002 \
+  --direction Inbound \
+  --protocol Tcp \
+  --access Allow \
+  --destination-port-ranges 443
+
+az network nsg rule create \
+  --resource-group OpenSignRG \
+  --nsg-name opensign-vmNSG \
+  --name Allow-Caddy-Internal \
+  --priority 1003 \
+  --direction Inbound \
+  --protocol Tcp \
+  --access Allow \
+  --destination-port-ranges 3001
+```
+
+---
+
+## 🌍 Step 3: Point Domain to VM
+
+In your DNS provider (e.g., GoDaddy, Cloudflare):
+
+- Add an **A record**:  
+  - Name: `opensign`  
+  - Value: `<your VM public IP>`  
+  - TTL: 1 min or Auto
+
+Let it propagate (~5–10 mins).
+
+---
+
+## 📦 Step 4: SSH into the VM
+
+```bash
+ssh azureuser@<your-vm-ip>
+```
+
+---
+
+## 🐳 Step 5: Install Docker + Compose V2
+
+```bash
+sudo apt update && sudo apt install docker.io -y
+
+# Install Compose V2 (CLI plugin)
+mkdir -p ~/.docker/cli-plugins/
+curl -SL https://github.com/docker/compose/releases/download/v2.24.5/docker-compose-linux-x86_64 -o ~/.docker/cli-plugins/docker-compose
+chmod +x ~/.docker/cli-plugins/docker-compose
+
+# Enable Docker
+sudo systemctl enable docker
+```
+
+Verify:
+```bash
+docker compose version
+```
+
+---
+
+## 📁 Step 6: Set Up Project and Volumes
+
+### 6.1 Create a working directory
+```bash
+mkdir opensign && cd opensign
+```
+
+### 6.2 Download files
+```bash
+export HOST_URL=https://opensign.yourdomain.com
+
+curl -O https://raw.githubusercontent.com/OpenSignLabs/OpenSign/main/docker-compose.yml
+curl -O https://raw.githubusercontent.com/OpenSignLabs/OpenSign/main/Caddyfile
+curl -O https://raw.githubusercontent.com/OpenSignLabs/OpenSign/main/.env.local_dev
+mv .env.local_dev .env.prod
+```
+Make sure that you update the SMTP settings by editing the .env.prod file in order to receive emails.
+---
+
+
+## ⚙️ Step 7: Start the Stack
+
+Now boot the containers using Compose V2:
+
+```bash
+docker compose up -d --force-recreate
+```
+
+---
+
+## ✅ Step 8: Verify Everything
+
+- `https://opensign.yourdomain.com` loads the app with HTTPS
+- Caddy fetched SSL certs automatically
+- Backend routes work at `/api/*`
+- MongoDB persists data
+- Uploaded files persist via `opensign-files` volume
+
+Test:
+
+```bash
+docker exec -it OpenSignServer-container ls /usr/src/app/files
+docker volume inspect opensign-files
+```
+
+---
+
+## 📦 Step 9: Auto-start on Reboot (optional)
+
+```bash
+crontab -e
+```
+
+Add:
+```bash
+@reboot cd /home/azureuser/opensign && docker compose up -d
+```
+
+---
+
+## 🔄 Backups (optional)
+
+```bash
+# Backup MongoDB volume
+docker run --rm -v opensign_data-volume:/data -v $(pwd):/backup ubuntu tar czvf /backup/mongo-backup.tar.gz /data
+
+# Backup OpenSign files
+docker run --rm -v opensign_opensign-files:/data -v $(pwd):/backup ubuntu tar czvf /backup/files-backup.tar.gz /data
+```
