 ### Build the Binary
 
 To build the binary, run the make build command from the project's root directory:
 
 ```makefile
-make build
+make GOARCH=$GOARCH build
 ```
 
 This command will build the binary and output it to the `/build/.out` directory.

 To build the NGINX Gateway Fabric and NGINX container images from source run the following make command:
 
 ```makefile
-make TAG=$(whoami) build-images
+make GOARCH=$GOARCH TAG=$(whoami) build-images
 ```
 
 This will build the docker images `nginx-gateway-fabric:<your-user>` and `nginx-gateway-fabric/nginx:<your-user>`.
