 ### Build from source
 
+Using Makefile (recommended):
+
 ```bash
+# Build static binary (production-ready, fully portable)
+make build
+
+# Build with debug symbols (development)
+make build-dev
+
+# Install to /usr/local/bin
+make install
+
+# Clean build artifacts
+make clean
+
+# Verify binary has no dependencies
+make verify-static
+
+# Show all available targets
+make help
+```
+
+Or using Go directly:
+
+```bash
+# Static binary (portable across all Linux x86-64 systems)
+CGO_ENABLED=0 go build -ldflags "-s -w" -trimpath -o ./build/entity-maker ./cmd/entity-maker
+
+# Development binary with debug symbols
 go build -o entity-maker ./cmd/entity-maker
 ```
 
+The static binary (`make build`) is **fully portable** and will run on any Linux x86-64 system without external dependencies.
