-# How to contribute to Datasets?
-[![Contributor Covenant](https://img.shields.io/badge/Contributor%20Covenant-2.0-4baaaa.svg)](CODE_OF_CONDUCT.md)
-
-Datasets is an open source project, so all contributions and suggestions are welcome.
-
-You can contribute in many different ways: giving ideas, answering questions, reporting bugs, proposing enhancements, 
-improving the documentation, fixing bugs,...
-
-Many thanks in advance to every contributor.
-
-In order to facilitate healthy, constructive behavior in an open and inclusive community, we all respect and abide by 
-our [code of conduct](CODE_OF_CONDUCT.md).
-
-## How to work on an open Issue?
-You have the list of open Issues at: https://github.com/huggingface/datasets/issues
-
-Some of them may have the label `help wanted`: that means that any contributor is welcomed!
-
-If you would like to work on any of the open Issues:
-
-1. Make sure it is not already assigned to someone else. You have the assignee (if any) on the top of the right column of the Issue page.
-
-2. You can self-assign it by commenting on the Issue page with one of the keywords: `#take` or `#self-assign`.
-
-3. Work on your self-assigned issue and eventually create a Pull Request.
-
-## How to create a Pull Request?
-1. Fork the [repository](https://github.com/huggingface/datasets) by clicking on the 'Fork' button on the repository's page. This creates a copy of the code under your GitHub user account.
-
-2. Clone your fork to your local disk, and add the base repository as a remote:
-
-	```bash
-	git clone git@github.com:<your Github handle>/datasets.git
-	cd datasets
-	git remote add upstream https://github.com/huggingface/datasets.git
-	```
-
-3. Create a new branch to hold your development changes:
-
-	```bash
-	git checkout -b a-descriptive-name-for-my-changes
-	```
-
-	**do not** work on the `main` branch.
-
-4. Set up a development environment by running the following command in a virtual environment:
-
-	```bash
-	pip install -e ".[dev]"
-	```
-
-   (If datasets was already installed in the virtual environment, remove
-   it with `pip uninstall datasets` before reinstalling it in editable
-   mode with the `-e` flag.)
-
-5. Develop the features on your branch. If you want to add a dataset see more in-detail instructions in the section [*How to add a dataset*](#how-to-add-a-dataset). 
-
-6. Format your code. Run black and isort so that your newly added files look nice with the following command:
-
-	```bash
-	make style
-	```
-
-7. Once you're happy with your dataset script file, add your changes and make a commit to record your changes locally:
-
-	```bash
-	git add datasets/<your_dataset_name>
-	git commit
-	```
-
-	It is a good idea to sync your copy of the code with the original
-	repository regularly. This way you can quickly account for changes:
-
-	```bash
-	git fetch upstream
-	git rebase upstream/main
-    ```
-
-   Push the changes to your account using:
-
-   ```bash
-   git push -u origin a-descriptive-name-for-my-changes
-   ```
-
-8. Once you are satisfied, go the webpage of your fork on GitHub. Click on "Pull request" to send your to the project maintainers for review.

-## How to add a dataset
-
-You can share your dataset on https://huggingface.co/datasets directly using your account, see the documentation:
-
-* [Create a dataset and upload files](https://huggingface.co/docs/datasets/upload_dataset)
-* [Advanced guide using dataset scripts](https://huggingface.co/docs/datasets/share)
-
-## How to contribute to the dataset cards
-
-Improving the documentation of datasets is an ever increasing effort and we invite users to contribute by sharing their insights with the community in the `README.md` dataset cards provided for each dataset.
-
-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 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.
-
-Finally, if you want more information on the how and why of dataset cards, we strongly recommend reading the foundational works [Datasheets for Datasets](https://arxiv.org/abs/1803.09010) and [Data Statements for NLP](https://www.aclweb.org/anthology/Q18-1041/).
-
-Thank you for your contribution!
