Updated toolchain installation walk-through.. no steps left out

[LlamabobAl2]

Hello, I'm trying to install the toolchain for the nRF9160.  I have the nRF9160 DK.   I installed Segger Embedded Studio for the nRF9160. 

I was able to install nRF Connect v3.4.1.   Under Toolchain Manager, I show 4 choices.  I installed the top one thinking it must be the newest.  nRF Connect SDK v1.3.0, and I see the "First steps to build" button.   

Under steps 3, I have no zephyr folder.  

Backing out to the "Getting Started Assistant" it warns not to use this tool, but rather go to the Toolchain Manager which is a dead-end.  

I also looked at the Youtube videos on the toolchain.   These were dated 2019, and are obsolete.   

Is there an updated step-by-step to follow to install the entire nRF9160 toolchain on a Windows 10 laptop?

Thanks, 
Bob

This comes close.

I made it through this page and on the next page "Building and programming a sample application",  in the section "Building on the command line",  I type 

west build -b nrf9160dk_nrf52840

and I can't get past this. 

I'm getting closer !!

I had this error as well. I have manually configured SDK and tool chain.

I did not have "ZEPHYR_TOOLCHAIN_VARIANT" and "GNUARMEMB_TOOLCHAIN_PATH" set.
