 #### Creating a Sysroot
 
-
 Start with a fresh Raspberry PI image:
-  - Use the  Raspberry pi imager from https://www.raspberrypi.org/software/
-  - Follow installation instructions from the CHIP BUILDING.md document. 
-    Generally this includes:
-    - Use Ubuntu 21.04 server 64 bit server image
-    - Install required compile dependencies via `apt-get`. You may skip 
-      installing git and python3 dependencies to save some image size
