 ### How to Contribute
 You can open a pull request to [hub-docs repository](https://github.com/huggingface/hub-docs) to contribute a new documentation about a new task. Under `tasks/src` we have a folder for every task that contains two files, `about.md` and `data.ts`. `about.md` contains the markdown part of the page, use cases, resources and minimal code block to infer a model that belongs to the task. `data.ts` contains redirections to canonical models and datasets, metrics, the schema of the task and the information the inference widget needs.

 We have `tasks/assets` that contains data used in the inference widget and images used in the markdown file. The last file is `const.ts`, which has the task to library mapping (e.g. spacy to token-classification) where you can add a library. They will look in the top right corner like below.

 This might seem overwhelming, but you don't necessarily need to add all of these in one pull request or on your own, you can simply contribute one section. Feel free to ask for help whenever you need.
