Hello,

Perhaps the talk on Geometry and Cell Optimization by Matt Watkins from the
last cp2k tutorial would be a good place to start.
    https://www.cp2k.org/events:2015_cecam_tutorial:index

However, if you are planning to study an ethanol dimer, you'll likely want
to do that in the gas phase, i.e. with vacuum on all sides of the molecule.
Simply choose a large enough cubic or orthorhombic box, sophisticated
tuning of the cell parameter should not be necessary.

Hope that helps,
Ralph
