document how to create a local copy of a nimble demo app #1977
Description
can someone please document how to crate a local instance of a demo app (i.e. btshell, etc) so one might locally modify the code.
The docs show referencing the git repo @apache-mynewt-nimble/apps/btshell but that omits the ability to edit/build the target.
there must be a simple way to fork one of these examples and build/edit it locally.
