Hi Tejas,

contributing to the Zephyr project works by sending pull-requests to one
of our repositories at GitHub [1]. There you can also file issues.
Helping hands are always welcome :-)
The easiest way to reach out to the community is via Slack.
You can join the slack channels with the invitation link [2].
