+# Talawa-Admin Service Setup Guide
+
+This guide outlines the steps to set up and manage the Talawa-Admin service on a Linux server using `systemd`.
+
+## Prerequisites
+
+- Firstly, You should have locally setup the Talawa-Admin repo using [Setting up this repository](#setting-up-this-repository)
+- Ensure **Node.js** and **npm** are correctly installed and available for the specified user and group.
+- It’s recommended to use **nvm** (Node Version Manager) for better management of different Node.js versions.
+- Ensure you have root or sudo access to configure systemd services.
+- Create a dedicated service user:
+   ```bash
+   sudo useradd -r -s /bin/false talawa_admin
+   sudo groupadd -r talawa_admin
+   sudo usermod -a -G talawa_admin talawa_admin
+   # Get the absolute path to your talawa-admin installation
+   INSTALL_PATH=$(pwd)
+
+   sudo chown -R talawa_admin:talawa_admin $INSTALL_PATH
+   sudo chmod 750 $INSTALL_PATH
+   sudo find $INSTALL_PATH -type f -exec chmod 640 {} \;
+   sudo chmod 600 $INSTALL_PATH/.env
+   ```
+
+---
+
+### Service Configuration
+
+#### 1. **Copy the `talawa_admin.service` file**
+   - Place the `talawa_admin.service` file in the appropriate systemd directory based on your Linux distribution:
+     - For most distributions: `/etc/systemd/system/`
+     - For systems using `systemd`, this will be the default directory.
+
+   <!-- Optional Steps -->
+   - Verify service file permissions and ownership:
+   ```bash
+   sudo chmod 644 /etc/systemd/system/talawa_admin.service
+   sudo chown root:root /etc/systemd/system/talawa_admin.service
+   sudo systemd-analyze verify talawa_admin.service
+   ```
+
+#### 2. **Verify the CODEROOT Path**
+   - Ensure that the `CODEROOT` environment variable matches the absolute path to the Talawa-Admin code directory.
+
+#### 3. **Set the Correct Working Directory**
+   - Always use the absolute path for the `WorkingDirectory`. Do **not** use `$CODEROOT` in the `WorkingDirectory` field.
+
+#### 4. **Ensure the `.env` File Exists**
+   - Verify that the path in the `EnvironmentFile` line points to a valid `.env` file located in the root directory of the Talawa-Admin repository.
+
+   <!-- Optional Steps -->
+   - Validate environment file permissions and configuration:
+   ```bash
+   sudo chmod 600 /path/to/talawa-admin/.env
+   sudo chown talawa_admin:talawa_admin /path/to/talawa-admin/.env
+   # Verify environment variables are loaded
+   sudo systemctl show-environment
+
+   ```
+
+#### 5. **Adjust User and Group**
+   - Modify the `User` and `Group` settings to match the user account intended to run the service.
+
+---
+
+### Steps to Enable and Manage the Service
+
+1. **Reload the systemd daemon** to apply changes:
+   ```bash
+   sudo systemctl daemon-reload
+   ```
+
+2. **Start the Talawa-Admin Service**:
+   ```bash
+   sudo systemctl start talawa_admin.service
+   # Verify service started successfully
+   sudo systemctl status talawa_admin.service
+   ```
+
+3. **Stop the Talawa-Admin Service**:
+   ```bash
+   sudo systemctl stop talawa_admin.service
+   ```
+
+4. **Enable the Service to Start on Boot**:
+   ```bash
+   sudo systemctl enable talawa_admin.service
+   ```
+
+---
+
+### Troubleshooting
+
+- If you encounter any issues, you can check the status and logs of the service:
+  ```bash
+  sudo systemctl status talawa_admin.service
+  sudo journalctl -u talawa_admin.service
+  ```
+
+---
+
+By following these steps, you can set up and manage the Talawa-Admin service efficiently on your Linux server.
