You can generate your own sitemap links easily by visiting:
https://www.xml-sitemaps.com/
These should crawl through your page and you can either download the page that has been created or open up a notepad/notepad++/any other text editor and save it as “sitemap.xml”.
Select the option for automatically choosing priorities for each webpage, as this will give the most authority to your Home page/index page, unless you prefer otherwise.
From here you can then just simply upload your new sitemap to the website by the C-Panel/FileZilla or any FTP uploading method you may use.
Want More?
<lastmod> can be added to the sitemap, this shows the search engine robots that may be crawling your website when each of the pages was last updated/modified.
Syntax:
<lastmod>2016-02-12T21:47:44+00:00</lastmod>
Format:YEAR-MON-DAY
