Inkscape's creation and development, as an Open Source project, is a community effort! It takes the time, knowledge, skills, motivation and passions of the whole community, to make Inkscape great. Your time invested in Inkscape can help the whole project move forwards and ultimately help the whole community of users and the wider world.
Contributors to the project are expected to be polite and professional and abide by the code of conduct. Even so, the project is often a fun place to be with friendly faces to go along with the interesting work. If you do have problem, don't hesitate to raise the issue with one of the moderators.
We use a couple of different places to work together. Most teams use the rocket chat to organise, but we also make use of video chat Big Blue Button for events, mailing lists for long form discussions.
We keep a calendar with the various teams' meeting times on the website. If you'd like to join a team, you should also subscribe to the calendar to be notified of the meetings.
If you are just starting out, ask about mentoring. The project runs several types of mentorship programs from Outreachy, to Google Summer of Code, to our more casual mentorships offered by fellow volunteers to help you get started contributing in the way you would like to. Ask for help!
