 # Deploy with SVR.JS
 
-TODO
+SVR.JS is web server software running on Node.JS. This tutorial will guide you on how to deploy MERNMail application with SVR.JS web server.
+
+Follow these steps to install and set up MERNMail with SVR.JS on GNU/Linux systems:
+
+## 1. Install SVR.JS
+
+First, install SVR.JS:
+
+```bash
+curl -fsSL https://downloads.svrjs.org/installer/svr.js.installer.linux.20240509.sh > /tmp/installer.sh && sudo bash /tmp/installer.sh
+```
+
+You can also copy the installation command from the [SVR.JS website](https://svrjs.org)
+
+## 2. Configure SVR.JS
+
+Open the `/etc/svrjs-config.json` file in your preferred text editor, and alter the configuration like this (`wwwroot` webroot property in the SVR.JS configuration serves as MERNMail application root):
+
+```json
+{
+  "customHeaders": {
+    "Strict-Transport-Security": "max-age=31536000; includeSubDomains; preload",
+    "x-content-type-options": "nosniff",
+    "Content-Security-Policy": "default-src 'self'; script-src 'self' 'sha256-VA8O2hAdooB288EpSTrGLl7z3QikbWU9wwoebO/QaYk=' 'sha256-+5XkZFazzJo8n0iOP4ti/cLCMUudTf//Mzkb7xNPXIc=' 'sha256-MS6/3FCg4WjP9gwgaBGwLpRCY6fZBgwmhVCdrPrNf3E=' 'sha256-tQjf8gvb2ROOMapIxFvFAYBeUJ0v1HCbOcSmDNXGtDo='; style-src 'self' 'unsafe-inline'; frame-src 'self' data:",
+    "Referrer-Policy": "strict-origin-when-cross-origin",
+    "Permissions-Policy": "geolocation=(), camera=(), microphone=(), fullscreen=*",
+    "Feature-Policy": "geolocation 'none', camera 'none', microphone 'none', fullscreen *"
+  },
+  "nonStandardCodes": [
+    {
+      "scode": 403,
+      "regex": "/^\\/\\.env(?:\\.local|\\.production)?(?:$|[#?])/"
+    },
+    {
+      "scode": 403,
+      "regex": "/^\\/\\.git/"
+    }
+  ],
+  "wwwroot": "/var/lib/mernmail",
+  ... other configuration options
+}
+```
+
+## 3. Set up MERNMail
+
+Run these commands to set up MERNMail:
+
+```bash
+cd /var/lib
+git clone https://git.svrjs.org/mernmail/mernmail.git
+chown -hR svrjs:svrjs /var/lib/mernmail
+cd mernmail
+sudo runuser svrjs -s /bin/bash -c 'cd /var/lib/mernmail && npm install && npm run build'
+```
+
+## 4. Configure MERNMail
+
+Copy the `.env.example` file to a `.env` file in the MERNMail root directory (like `/var/lib/mernmail`). The configuration options can be found in the [/docs/configuration](Configuration) page.
+
+For additional security, you can set the permissions for the `.env` file using this command:
+```bash
+sudo chmod 600 /var/lib/mernmail/.env
+```
+
+## 5. Install MERNMail integration mod
+
+Run these commands to install the MERNMail integration mod for SVR.JS (replace `/usr/lib/svrjs` with SVR.JS installation directory):
+
+```bash
+cd ~
+git clone https://git.svrjs.org/mernmail/mernmail-svrjs-mod.git
+cd mernmail-svrjs-integration
+npm install
+npm run build
+cp dist/mod.js /usr/lib/svrjs/mods/mernmail.js
+```
+
+## 6. Restart SVR.JS
+
+Restart SVR.JS using either `sudo systemctl restart svrjs` or `sudo /etc/init.d/svrjs restart` command.
