+## Caveats
+
+These dotfiles assume the computer is set up in a specific way. I recommend
+using Ansible or other tools (Chef, Puppet, etc) to automatically provision
+your computer the way you like it.
+
+The following should really be Ansible playbooks:
+
+- mail (setup systemd units)
+- ssh (add ssh keys & server aliases)
+- system (modify files out of `$HOME`)
+
