Beware and avoid leaking sensitive data.
Options:
- ensure wpcarro/dotfiles remains private while support potentially
sensitive documents
- consider encrypting sensitive documents using gnupg or git-crypt
- consider having someone from the Security team audit the repository to
ensure that nothing sensitive is being leaked
