For each active instance of emacs:

open up the file called instances.txt
make a new entry
(keywords describing what you're doing with the files that are open)
press M-x jp (journal print open file paths)
save it

also check the launch.sh script for that context
describe the workspace state
and make sure everything open is noted there.

close emacs (repeat for any other emacs open)
