+# MinIO Installation and Configuration Guide
+
+This document outlines the steps to install and configure a standalone MinIO server, running as a `systemd` service.
+
+## 1. Download MinIO Binary
+
+Download the latest MinIO server executable and make it accessible system-wide.
+
+```bash
+sudo wget https://dl.min.io/server/minio/release/linux-amd64/minio -O /usr/local/bin/minio
+sudo chmod +x /usr/local/bin/minio
+```
+
+## 2. Create a Dedicated User
+
+For security, create a dedicated system user and group that will own and run the MinIO process. This user does not have login privileges.
+
+```bash
+sudo useradd -r -s /bin/false minio-user
+```
+
+## 3. Create Data and Configuration Directories
+
+Create the directories specified for MinIO's configuration and its backend storage. Assign ownership to the `minio-user`.
+
+```bash
+# Create directories
+sudo mkdir -p /opt/calypso/conf/minio /opt/calypso/data/storage/s3
+
+# Set ownership
+sudo chown -R minio-user:minio-user /opt/calypso/conf/minio /opt/calypso/data/storage/s3
+```
+
+## 4. Create Environment Configuration File
+
+Create a configuration file that will be used by the `systemd` service to set necessary environment variables. This includes the access credentials and the path to the storage volume.
+
+**Note:** The following command includes a pre-generated secure password. These credentials will be required to log in to the MinIO console.
+
+```bash
+# Create the environment file
+sudo bash -c "cat > /opt/calypso/conf/minio/minio.conf" <<'EOF'
+MINIO_ROOT_USER=admin
+MINIO_ROOT_PASSWORD=HqBX1IINqFynkWFa
+MINIO_VOLUMES=/opt/calypso/data/storage/s3
+EOF
+
+# Set ownership of the file
+sudo chown minio-user:minio-user /opt/calypso/conf/minio/minio.conf
+```
+
+## 5. Create Systemd Service File
+
+Create a `systemd` service file to manage the MinIO server process. This defines how the server is started, stopped, and managed.
+
+```bash
+sudo bash -c "cat > /etc/systemd/system/minio.service" <<'EOF'
+[Unit]
+Description=MinIO
+Documentation=https://min.io/docs/minio/linux/index.html
+Wants=network-online.target
+After=network-online.target
+AssertFileIsExecutable=/usr/local/bin/minio
+
+[Service]
+Type=simple
+User=minio-user
+Group=minio-user
+EnvironmentFile=/opt/calypso/conf/minio/minio.conf
+ExecStart=/usr/local/bin/minio server --console-address ":9001" $MINIO_VOLUMES
+Restart=always
+LimitNOFILE=65536
+TimeoutStopSec=300
+
+[Install]
+WantedBy=multi-user.target
+EOF
+```
+
+## 6. Start and Enable the MinIO Service
+
+Reload the `systemd` daemon to recognize the new service file, enable it to start automatically on boot, and then start the service.
+
+```bash
+sudo systemctl daemon-reload
+sudo systemctl enable minio.service
+sudo systemctl start minio.service
+```
+
+## 7. Access MinIO
+
+The MinIO server is now running.
