+### On Windows
+While installing and building natively on zephyr is supported as described at: https://docs.zephyrproject.org/latest/develop/getting_started/index.html. 
+
+Arduino currently has not ported their build setup to the Windows environment.  However it is possible to setup and build the loaders on a Windows system using WSL and use the resulting Loader files within Windows.  You will need to follow the instructions given above
+for installing on Ubuntu.
+
+There are at least two strategies. 
+1) Install the sources in the native Windows filesystem (NTFS, FAT32, etc) and within WSL, cd to the root directory where you installed your sources, like: /mnt/d/github/ArduinoCore-zephyr.
+
+2) Install the sources within the WSL file system, like: ~/git/ArduinoCore-zephyr
+
+There are pros and cons to both strategies.  With 1) Builds are relatively very slow, but once done you can use it directly within
+Arduino.  With 2) Builds are a lot faster, however, you then need to copy the resulting build back to somewhere in your windows directory
+structure.  It is this location, that you will add to the Arduino IDE as mentioned below in the section: Using the core in Arduino IDE/CLI
+
+In either strategy, you may have to update the link: cores\arduino\api as sometimes this link file may or may not work properly.

 ### Run the ```bootstrap``` script
 ```bash
 cd ArduinoCore-zephyr
