Rosetta sites are the local WordPress.org sites and they are a great way to grow your local community.
Everything you post on your Rosetta site will go into the news feed of every WordPress installation that runs in your language. That make the blog content of the Rosetta site a great channel to communicate location-specific content in your language – from WordPress updates to local events like meetups and WordCamps. This page will give you some suggestions on great content for your local WordPress.org site.
Join your local Slack team (if there is one) or any other communication channel (Facebook, Meetup.com, IRC).
Create a profile on make.wordpress.org. What do you need to do right away (use your name, Gravatar, short bio), why you should become a contributor, why you shouldn’t.
Organize a Contributor Day. Stand-alone contributor days are a great way to get people involved. Organizing one is pretty easy and very rewarding for everyone involved.

WordPress is working toward a community agreed-upon basic text for CoC: feel free to adapt it, based on your cultural differences and translate into your language. There should be one readily available and translated, so you can use it for local events around the country.
