Culture is not a physical thing. You can't touch culture. You can see it reflected in things like visual arts, clothing, books, code, UX, and so much else, but culture itself is not an exterior object that can be seen and measured with some scientific apparatus.
Culture is interior; it lives inside each member of a group. It's what it means when we say "we". It's first-person, plural. Culture is a set of stories or perspectives, shared by a group, that help to define both how to behave within that group, and how it feels to be part of that group.
I want to create a culture at Grace that lives up to its name. We all deserve it.
Be graceful in your interactions here.
Give grace to everyone participating with us.
Create something together that embodies grace in its design and form.
When in doubt, remember the name of the project.
To be clear: if your behavior is more disruptive than constructive, you will be asked to leave.
