After pull the project, you need to add build file.

After build the project you can flash the project to device.

If you see log like this, the flash has completed successfully.

```
-- west flash: using runner nrfutil
-- runners.nrfutil: reset after flashing requested
-- runners.nrfutil: Flashing file: D:\CocoLinx\Projects\Csom\csom_v1_examples\helloworld\build\merged.hex
