@benjamincanac, is it possible to use local plugins in a similar way that Nuxt.js modules? For example:

/// nuxt.config.js
export default {
  content: {
    markdown: {
      remarkPlugins: [
        "~/plugins/remark-plugin.js",
      ],
      rehypePlugins: [
        ["~/plugins/rehype-plugin.js", { option: 2 }],
      ],
    },
  },
};

@juliomrqz Indeed it will be! You can already try this PR.
