cat << EOF > I_HAVE_BOOTSTRAPPED_OK
Tachi was bootstrapped here on $(date).

The existence of this file stops Tachi from bootstrapping again.
There's nothing harmful about this -- you can bootstrap as much as you want!
We just don't want to necessarily bootstrap *each* time we boot Tachi.

To bootstrap again (incase you think something has gone wrong)
Delete this file and re-run npm start.
