+# NX9 DNS Server Installation Guide
+
+## Installation Methods
+
+The NX9 DNS Server provides three flexible installation methods:
+
+### 1. Direct Installation Script
+
+The `install.sh` script provides a customizable installation process:
+
+```bash
+# Default installation to /usr/local
+./install.sh
+
+# Custom installation prefix
+./install.sh --prefix=/opt/nx9-dns
+```
+
+#### Features:
+- Configurable installation prefix
+- Automatic service setup
+- Documentation and man page installation
+- Proper permission handling
+
+### 2. Debian Package Installation
+
+For Debian-based systems (Ubuntu, Debian, etc.):
+
+```bash
+# Build the package
+./build-deb.sh
+
+# Install the generated package
+sudo dpkg -i nx9-dns-server-*.deb
+```
+
+#### Package Features:
+- Proper dependency management
+- System user creation
+- Systemd service integration
+- Configuration file management
+- Clean uninstallation support
+
+### 3. RPM Package Installation
+
+For RPM-based systems (RHEL, CentOS, Fedora):
+
+```bash
+# Build the package
+./build-rpm.sh
+
+# Install the generated package
+sudo rpm -i nx9-dns-server-*.rpm
+```
+
+#### Package Features:
+- Automatic dependency resolution
+- System service management
+- Standard RPM filesystem hierarchy
+- Built-in upgrade support
+
+## Directory Structure
+
+The installation creates the following directory structure:
+
+```
+${PREFIX}/
+├── bin/
+│   └── nx9-dns-server
+├── lib/
+│   └── nx9-dns-server/
+├── etc/
+│   └── nx9-dns-server/
+│       └── nx9-dns-server.conf
+├── share/
+│   ├── doc/
+│   │   └── nx9-dns-server/
+│   │       ├── README.md
+│   │       └── LICENSE
+│   └── man/
+│       └── man1/
+│           └── nx9-dns-server.1.gz
+└── var/
+    └── lib/
+        └── nx9-dns-server/
+            └── dns.db
+```
+
+## System Integration
+
+### Service Management
+After installation, the server runs as a systemd service:
+
+```bash
+# Start the service
+sudo systemctl start nx9-dns-server
+
+# Enable auto-start at boot
+sudo systemctl enable nx9-dns-server
+
+# Check service status
+sudo systemctl status nx9-dns-server
+```
+
+### Security Features
+- Dedicated system user (`nx9-dns`)
+- Proper file permissions
+- Confined service execution
+
+### Configuration
+- Main configuration: `/etc/nx9-dns-server/nx9-dns-server.conf`
+- Database location: `/var/lib/nx9-dns-server/dns.db`
+- DNSSEC key file: `/etc/nx9-dns-server/dnssec.key`
+
+## Uninstallation
+
+### Using Installation Script
+```bash
+# If installed with install.sh, manually remove files from prefix
+sudo rm -rf ${PREFIX}/{bin,lib,etc,share}/nx9-dns-server
+```
+
+### Package-based Removal
+```bash
+# Debian systems
+sudo apt remove nx9-dns-server
+
+# RPM systems
+sudo rpm -e nx9-dns-server
+```
+
+## Notes
+- All installation methods require root/sudo privileges
+- The installation preserves existing configuration files
+- Service user is created automatically
+- Logs are integrated with systemd journal
+
+This installation system follows standard Unix filesystem hierarchy and packaging conventions, making it suitable for both development and production environments.
