The documentation is not written yet.

opsty is in phase 1. It runs, but it is not released, so there is nothing here that would still be true by the time you could install it. Until then:

• The repository — README covers shell integration and the lamp
• The privacy page — the one network request, written down
• The front page

This page exists so the link in the README is never a 404. It is the same reason opsty.sh already answers with a script that tells you there is nothing to install.
