This, absolutely.<p>Communities can be healthy without a CoC, or unhealthy with one.  But having a CoC sends a big, clear message to women and other groups frequently marginalized in the tech scene that your project is healthy and welcoming.<p>Here&#x27;s why that&#x27;s a big deal: joining an open source project is an investment.  If you are a woman, or black, or trans, or god forbid, some combination thereof in tech, you really don&#x27;t want to become invested in a community that will at some point treat you like shit.  And let&#x27;s be real guys, many, many communities do treat women and minorities like shit.<p>A CoC, and just as importantly, the discussion surrounding one, is a simple sign that a community is a place where you can be a woman or a minority and contribute to open source without fear of harassment, abuse, marginalization, and other dangers faced by non-white-dudes in tech.
