I'm not familiar enough with Wikisource to evaluate this guide, but I'm forwarding it in case others are interested. Please direct questions and comments to Ananth.
We all know that Wikisource is one of the trending Wikimedia projects. We
are getting many new editors and new books to Indic language Wikisource's.
At the same time, we even noticed that there are many problems faced by the
new editors and a few of the existing editors. To help all of the editors
we have created a Handbook titled as *Wikisource Handbook for Indic
communities
<https://commons.wikimedia.org/wiki/File:Wikisource_Handbook_for_Indian_Communities.pdf>.
*Which is now available[1] to everyone to make the best use of it. I
request everyone to share this with all those who are in need of support in
editing Wikisource.
Authors of the book: Bodhisattwa Mandal and Ananth Subray P V.
