 ## Dataset card metadata
 
-A dataset repo will render its README.md as a dataset card. To control how the Hub displays the card, you should create a YAML section in the README file to define some metadata. Start by adding three --- at the top, then include all of the relevant metadata, and close the section with another group of --- like the example below:

+
+The metadata that you add to the dataset card enables certain interactions on the Hub. For example:
+
+- Allow users to filter and discover datasets at https://huggingface.co/datasets.
+  
+- If you choose a license using the keywords listed in the right column of this table, the license will be displayed on the dataset page.
+
+When creating a README.md file in a dataset repository on the Hub, use Metadata UI to fill the main metadata:
+
+To see metadata fields, see the detailed dataset card metadata specification here.
+
+### Dataset card creation guide
+
+For a step-by-step guide on creating a dataset card, check out the Create a dataset card guide. 
+
+Reading through existing dataset cards, such as the ELI5 dataset card, is a great way to familiarize yourself with the common conventions.
+
+### Linking a Paper
+
+If the dataset card includes a link to a paper on arXiv, the Hub will extract the arXiv ID and include it in the dataset tags with the format `arxiv:<PAPER ID>`. Clicking on the tag will let you:
+
+- Visit the Paper page
+  
+- Filter for other models on the Hub that cite the same paper.
