 The application consists of four main components:
 
-1. **VPP Stats Client** (`vppstats/`): Connects to VPP stats socket and retrieves interface counters
-2. **Interface MIB** (`ifmib/`): Maps VPP statistics to SNMP IF-MIB structure
-3. **AgentX Client** (`agentx/`): Handles AgentX protocol connection and MIB registration
-4. **Main Application**: Orchestrates the components and handles configuration

 ## Build Instructions
 
 ### Development Build
 
 ```bash
-go build -o govpp-snmp-agentx .
+# Build the binary
+make build
+
+# Run tests
+make test
 ```
 
-### Static Binary Build
+### Manual Build
 
-For deployment without Go runtime dependencies:
+If you prefer to use Go directly:
 
 ```bash
-# Linux static binary
-CGO_ENABLED=0 GOOS=linux go build -a -ldflags '-extldflags "-static"' -o govpp-snmp-agentx .
-
-# Cross-compile for different architectures
-CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -a -ldflags '-extldflags "-static"' -o govpp-snmp-agentx-linux-amd64 .
-CGO_ENABLED=0 GOOS=linux GOARCH=arm64 go build -a -ldflags '-extldflags "-static"' -o govpp-snmp-agentx-linux-arm64 .
+cd src && go build -o ../govpp-snmp-agentx .
 ```
 
-### Release Build with Version Info
+### Debian Package
+
+Build a Debian package for easy installation and deployment:
 
 ```bash
-VERSION=$(git describe --tags --always --dirty)
-BUILD_TIME=$(date -u '+%Y-%m-%d_%H:%M:%S')
-CGO_ENABLED=0 go build -ldflags "-X main.version=${VERSION} -X main.buildTime=${BUILD_TIME}" -o govpp-snmp-agentx .
+# Build the Debian package
+make pkg-deb
+
+# Install the package
+sudo dpkg -i ../govpp-snmp-agentx_*.deb
 ```
 
+The Debian package includes:
+- Binary installed to `/usr/sbin/govpp-snmp-agentx`
+- Systemd service file
+- Configuration file at `/etc/default/govpp-snmp-agentx`
+- Manual page
+
