Create README.md
@ManuelFay thanks you so much for adding a dataset card, this is such a cool contribution!

This looks like it uses an old template for the card we've moved things around a bit and we have an app you should be using to get the tags and the structure of the Data Fields paragraph :) Would you mind moving your text to the newer format (we're also asking contributors to keep the full template structure, even if some sections still have [More Information Needed] for the time being)

Here's the link to the instructions:
https://github.com/huggingface/datasets/blob/master/ADD_NEW_DATASET.md#tag-the-dataset-and-write-the-dataset-card

Out of curiosity, what was your landing point for filling out the card? Did you follow the "Update on Github" when navigating the datasets? Trying to make the instructions as clear as possible :)  @yjernite 

Perfect, I'll follow the instructions when I have a bit more time tomorrow ! I was actually browsing the new contributions after the dataset sprint and realized most of the "old" datasets were not tagged, so I just copied and pasted the readme from another dataset and was not aware there was precise instructions... Will fix !

BTW, amazing job with the retriBert work, I used the contrastive + in-batch negative quite a bit for various projects. Probably neither the time nor place to talk about that but I was curious as to why, in your original work, you prefered using a simple projection in the last layer to differentiate the question vs answer embedding, rather than allowing for bias in the dense layer or even just to fine-tune 2 different embedders for question + answer ?  Cool! Looking forward to the next version!

Quick answer for retriBERT is that I expected a simple projection to generalize better and more importantly only having to store the gradients for the proj means training with larger batches :) If you want to keep chatting about it, feel free to send me an email! Hi @ManuelFay ! 
If you're still interested in completing the FQuAD dataset card, note that we've generated one that is pre-filled.
Therefore feel free to complete it with the content you already have in your README.md.
This would be awesome ! And thanks again for your contribution :) Yo @lhoestq , just not sure about the tag table at the top, I used @yjernite eli5 template so hope it's okay ! Also want to signal the streamlit app for dataset tagging has a weird behavior with the size categories when filling in the form. 

Thanks to you guys for doing that and sorry about the time it took, i completely forgot about it !
