Most Wikipedia and Wikimedia projects have a very little focus on building educational content for new contributors. It's time to recognize the lack of such resources as a movement-level gap that affects bringing new blood in the community. Though simply having the user guides does not solve the issues of sustainability of new editors, it is a good starting point.
The Odia Wikimedians User Group started working shyly on a project to create video tutorials for the new editors. Though providing good quality user guide was always a focus for the community since the very beginning, video tutorials were never given too much of importance and hence there were only a handful of those because of the interest of a few Wikipedians.
The idea to create some good quality short video tutorials was discussed in 2016 and then later got emphasized by a relatively new Wikipedian User:Soumendrak in early 2019. The project is shaping up with an emphasis on storytelling and not just a guide with on-screen action. People, after all, are in the core of the Wikimedia movement.
