 ### Development Process
 
 Clone this repo onto your development/build machine and the raspberry pi that controls the Xilinx 7000 board

+On the dev machine, the below script builds zc706 and secure copies it to the target pi (in your pi $HOME directory):
 ```shell
-cd ~/zc706
-./build.sh $your_user/ssh_id
+cd ~/zynq-rs
+./build.sh $your_user_or_ssh_id
 ```
 
 On the pi, we need an information rich environment that includes a relatively reliable `gdb` experience (that includes `ctrl-p` and `ctrl-n` command history that persists across `cgdb` executions), run:
 ```shell
 ssh pi4
-cd zc706
+cd zynq-rs
+# For ZC706, run:
+./tmux.sh 0
+# For Cora Z7, run:
 ./tmux.sh
