A method, for anyone who wants to do this and does not know where to start.
Photograph the village gate and everything written on it. Photograph any memorial, plaque or inscription, including the ones nobody reads, and photograph them straight on and close enough to read.
Find the oldest building and ask who looks after it. Find the jathera and ask whose it is. Find out whether the pond is still cleaned and when it stopped.
Ask three old people the same four questions: what is the oldest thing here, who left and when, what do people still argue about, and what was here that is gone. Record the answers on a phone and note the person's name and age and whether they agree to be named.
Look up the village in the district gazetteer and the settlement report for its district. Most are digitised and free. Note where the written record and the spoken one disagree, because that gap is usually the interesting part.
Write it down with what you do not know clearly marked. An account with holes in it that says where the holes are is worth more than a smooth one that has filled them in.
Then send it, so that the next person does not have to start again.
Start with what is physical and dated: an inscription, a memorial, a foundation stone, a gate, a milestone. Photograph it with something for scale and note where it is.
Then ask the oldest people, one at a time and separately, and write down who said what. Two accounts that differ are more useful than one account that is agreed.
Then say what you could not find out. A record that marks its own gaps can be completed by somebody else, and one that hides them cannot.
