## Objective

Build HTML documentation form Markdown source using Docusaurus, and can even embed JSX components into your Markdown thanks to MDX.

In order to build Docusaurus, the user must `init` a Docusaurus project, checkout the [documentation](https://docusaurus.io/docs/installation){:target="_blank"}. 

## How to use it

1. Ensure that your project has [`package.json`](https://docs.npmjs.com/cli/v6/configuring-npm/package-json){:target="_blank"}

      file.

1. Check the Docusaurus [documentation](https://docusaurus.io/docs){:target="_blank"} to install and configure a Docusaurus project.

1. Add this job URL inside the `include` list of your `.gitlab-ci.yml` file (see the [quick setup](/use-the-hub/#quick-setup)). You can specify [a fixed version](#changelog) instead of `latest`.

    ```yaml

      - remote: 'https://jobs.r2devops.io/latest/docusaurus_build.yml'

    ```

1. If you need to customize the job (stage, variables, ...) 👉 check the [jobs

   customization](/use-the-hub/#jobs-customization)

1. Well done, your job is ready to work ! 😀
