Generate a sitemap for the gitbook website in ./sitemap.xml.
Instead of using only the hostname part of the given config, this plugin uses the prefix of the urls.
Add it to your book.json with a basic configuration:
{
"plugins": ["sitemap-general"],
"pluginsConfig": {
"sitemap-general": {
"prefix": "https://cyberzhg.gitbooks.io/clrs/content/"
}
}
}
