Go take a look at the format for documenting found (relevant) datasets here: <https://github.com/datameet/india-election-data/blob/master/data-doc-format.md>. Use the same format to document the datasets, and then push the actual data file into the repository as well. Please remember to name the data file and the documentation file in a similar way. Mark required data cleaning/reorganisation/clarification tasks by opening an issue (where the name of the data file is mentioned).
