+If you see that a dataset card is missing information that you are in a position to provide (as an author of the dataset or as an experienced user), the best thing you can do is to open a Pull Request on the Hugging Face Hub. To do, go to the "Files and versions" tab of the dataset page and edit the `README.md` file. We provide:
 
 * a [template](https://github.com/huggingface/datasets/blob/main/templates/README.md)
 * a [guide](https://github.com/huggingface/datasets/blob/main/templates/README_guide.md) describing what information should go into each of the paragraphs
 * and if you need inspiration, we recommend looking through a [completed example](https://github.com/huggingface/datasets/blob/main/datasets/eli5/README.md)
 
-Note that datasets that are outside of a namespace (`squad`, `imagenet-1k`, etc.) are maintained on GitHub. In this case you have to open a Pull request on GitHub to edit the file at `datasets/<dataset-name>/README.md`.

 If you are a **dataset author**... you know what to do, it is your dataset after all ;) ! We would especially appreciate if you could help us fill in information about the process of creating the dataset, and take a moment to reflect on its social impact and possible limitations if you haven't already done so in the dataset paper or in another data statement.
 
 If you are a **user of a dataset**, the main source of information should be the dataset paper if it is available: we recommend pulling information from there into the relevant paragraphs of the template. We also eagerly welcome discussions on the [Considerations for Using the Data](https://github.com/huggingface/datasets/blob/main/templates/README_guide.md#considerations-for-using-the-data) based on existing scholarship or personal experience that would benefit the whole community.
