            <p>
                Before you get involved in Apache Ignite development, please sign up to the
                <a href="mailto:dev@ignite.apache.org">dev mailing list</a> and say "Hello" to everyone in
                the community. Tell us as much as you can about your areas of expertise mentioning how
                exactly you would like to contribute. We are a friendly and inclusive community and will try to
                simplify your "onboarding" considering your strengths or areas of interest.

                Also, make sure to share your JIRA ID in the same email
                (<a href="https://issues.apache.org/jira/projects/IGNITE"target="_blank">create a new one</a>
                if you don't have an ASF JIRA account yet). One of our community members will add you to
                the contributors' list and you will be able to go ahead and book Ignite tasks you'd like to work on.
                </li>
            </p>
            <p>
                Again, a small formality, you need to subscribe to the dev list before sending emails to it. To
                subscribe, send an empty email to <a
                    href="mailto:dev-subscribe@ignite.apache.org?subject=Subscribe"><nobr>dev-subscribe@ignite.apache.org</nobr></a>
                and follow simple instructions in the reply.
            </p>
            <p>
                Finally, check <a href="https://cwiki.apache.org/confluence/display/IGNITE/How+to+Collaborate" target="_blank">
                How to Collaborate</a> page for more details on various communication channels used by the community
                members. Even though most of the discussions take place on the dev list, we hang out in Slack.
            </p>
            <div class="page-heading">Contribution Process</div>
            <p>
                Before you start contributing, spend some time to get to know our

                    Development</a> process. In short, our communication and collaboration are based on

                us, as a group of professionals, drive the project forward in a respectful and inclusive way.

            <div class="page-heading">Become a Committer and PMC Member</div>
            <p>
                We love contributions and gladly promote active contributors to committers and PMC members! If you
                are new to Apache Software Foundation then Ignite will be an excellent
            </p>
            <p>
                The most important point of becoming a committer for Apache projects is active participation
                within the community. Being an active community member means participating in mailing list
                discussions, helping to answer questions, being respectful towards others, and following the
                meritocratic principles of community management.
            </p>
            <p>
                Of course, code contributions are also important. Once you make a few code contributions,
                you will become eligible to join Ignite committers, and possibly Ignite PMC.
                Candidates for new committers or PMC members are suggested by the current committers, mentors, or
                PMC members, and then must be approved by the PMC voting process.

                    This page</a> explains how and when Ignite community members decide to propose contributors to
                the roles of committers or PMC members.

                Apache Ignite uses GIT for its VCS system. The "master" branch contains the last released version.
                The "ignite-{version}" branch contains the latest code for the latest or upcoming release.
