[ree-gupta]

I believe spreadsheets are the most common data format and this could in the general section. Resources:

• Spreadsheet Best Practices - UC Davis Lab
• [Best Practices in Data Organisation Using Spreadsheets - University of South Hampton](https://southampton-rsg.github.io/spreadsheets-data-organisation-and-management/

@MalikaIhle Would it make sense to give me write access to this repo or do I create a fork and create PRs in future?

@ree-gupta oh wait - this repo is currently being maintained over there: https://github.com/MPDL/FAIR-Data-Management and will be pushed back to ours end of February after which you'd have writing access.

Maybe good if you attend that meeting for the 'passing over':

ping @LeimLarissa

This is when we will discuss further developement for this repo and how to keep our version synchronised. As for how to work with our repo, @NeuroShepherd is building a manual: he wants us to create branches and merge those. We will onboard you properly on that front soon.
