Hello Kurt W.

When your publish your website through Website X5 it asks you to Submit your sitemap on Google. Click on it then you will be redirected to Google Search Console page and your sitemap.xml should be automatically submitted by Website X5.

You can do it manually.

Visit Google Webmaster Page - https://www.google.com/webmasters/tools/ To add a new property or verify your website to Google just click on Add a property>Then enter your website url like http://www.yourwebsite.com>Then you will be redirected to verification page>There you will see that Google recommends you to download a HTML verification file>Download it>Then open your Website X5 Pro>Go to step 5-Export>Now upload the html file you have downloaded>Then export it again>Now click on Add your Sitemap to Google>Your sitemap will be published successfully

If you want to upload your sitemap manually then after verification of your website by google click on your website in the Search Console page>Then click on the Crawl (appears in left side bar)>Select Sitemaps>Click on Add/Test Sitemap>Then just enter sitemap.xml>Then submit>Then refresh the page and you will see your sitemap updated successfully

Do remeber that sitemap appears as sitemap.xml nor in html and the sitemap generated by Website X5 is supported by Google.

If you have more query regarding this, keep asking

Thank you

You can also use a third party generator such as xml-sitemaps.com; then ftp the file it generates to your website. Filezilla is a good ftp tool.
