this is the npm module to convert to pdf

https://www.npmjs.com/package/docsify-pdf-converter

and here is what I have as the setting

module.exports = {
  contents: [ "summary.md" ], // array of "table of contents" files path
  pathToPublic: "pdf/readme.pdf", // path where pdf will stored
  pdfOptions: "", // reference: https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md#pagepdfoptions
  removeTemp: true, // remove generated .md and .html or not
  emulateMedia: "screen", // mediaType, emulating by puppeteer for rendering pdf, 'print' by default (reference: https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md#pageemulatemediamediatype)
}

我觉得完全可以加上一下export to pdf的相关指导，起码我这种喜欢pdf的会觉得不错
