+You can also develop using a non-release version of Boundary - bypassing the
+above CLI download behavior - by manually placing the version of Boundary that
+you want to develop with in the `electron-app/cli/` directly (you may need to
+create the directory).

+After doing this, run yarn with `BYPASS_CLI_SETUP=true`; example:
