+# Deploy with PM2 + NGINX
+
+PM2 is a process manager for Node.JS applications with a built-in load balancer. NGINX is a popular web server and reverse proxy software. This tutorial will guide you on how to deploy MERNMail application with PM2 and NGINX on GNU/Linux systems.
+
+## 1. Clone the Repository
+
+First, change your working directory to your home directory, and clone the MERNMail repository:
+
+```bash
+cd ~
+git clone https://git.svrjs.org/mernmail/mernmail.git
+cd mernmail
+```
+
+## 2. Install Dependencies and Build the Application
+
+Navigate to the project directory, install the necessary dependencies, and build the MERNMail application:
+
+```bash
+npm install
+npm run build
+```
+
+## 3. Configuration
+
+Copy the `.env.example` file to a `.env` file in the root directory of the project. The configuration options can be found in the [Configuration](/docs/configuration) page.
+
+## 4. Install and Set Up PM2
+
+Install and set up PM2:
+
+```bash
+npm install -g pm2
+pm2 start npm --name "MERNMail" --start
+pm2 startup
+```
+
+After running the `pm2 startup` command, run the command shown in the output to the terminal to start the PM2 daemon when the OS boots up.
+
+## 5. Install and Set Up NGINX
+
+Install NGINX using `sudo apt install nginx` on Debian-based systems, `sudo pacman -S nginx` on Arch-based systems, or `sudo dnf install nginx` on Red Hat-based systems.
+
+After installing NGINX, open your preferred text editor, and save these contents to the `/etc/nginx/sites-available/mernmail` file (replace `/home/user` with path to your home directory; also check the port the MERNMail application listens to; this configuration causes NGINX to only listen to port 80):
+
+```nginx
+server {
+    listen 80;
+    server_name _;
+
+    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload";
+    add_header x-content-type-options "nosniff";

+    add_header Feature-Policy "geolocation 'none', camera 'none', microphone 'none', fullscreen *";
+
+    location /api/ {
+        proxy_pass http://localhost:3000/api/;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_cache_bypass $http_upgrade;
+    }
+
+    location / {
+        root /home/user/mernmail/frontend/dist;
+        try_files $uri $uri/ =404;
+    }
+}
+```
+
+After creating the NGINX configuration file, run these commands to enable the new NGINX configuration:
+```bash
+sudo rm /etc/nginx/sites-enabled/*
+sudo ln -s /etc/nginx/sites-available/mernmail /etc/nginx/sites-enabled/mernmail
+```
+
+## 6. Restart NGINX
+
+Restart NGINX using either `sudo systemctl restart nginx` or `sudo /etc/init.d/nginx restart` command.
