So I need 3 machine right?

- 1 to create golden image
- 1 to install mender-convert
- 1 is the target machine

But I have a few question:  
I have 2 .mender files which one I can use to upload to [hosted.mender.io](http://hosted.mender.io)?

After I use mender-convert, there is only 4 files, there is no .sdimg file, but I only need the _debian9\_nginx\_01-x86\_64-mender.ext4_ to flash the target machine and I’m good to go right?

But I’m using Debian, in Debian it doesn’t have live system like Ubuntu (like this [INTEL NUC x86-64 Ubuntu 18.04](https://hub.mender.io/t/intel-nuc-x86-64-ubuntu-18-04/2214)), can I copy _debian9\_nginx\_01-x86\_64-mender.ext4_ to a USB Flash Drive, plug it in the target machine and flash it from there?

And after I’ve flashed the targer machine, I’ll have a Device connect to [hosted.mender.io](http://hosted.mender.io) right?

And I can now use 1 of the 2 .mender file to create a deployment from mender right?
