Getting Started
To start using SiteTree you have to go only through three swift steps: installation, activation and enabling of the sitemaps.
Installation
Before you proceed, you have to know that SiteTree cannot run on versions of WordPress older than WordPress 5.2. However don't worry, SiteTree will warn you if there are environment incompatibilities.
To instal it you just have to unzip and upload the sitetree
folder in the /wp-content/plugins/
directory.
Activation
This step begins with locating SiteTree in the list of plugins and ends with a click on 'Activate'. As soon as the activation is complete, you will be promptly redirected to the 'SiteTree Dashboard'.
Enabling of the Sitemaps
From the 'SiteTree Dashboard' you can enable one or both sitemaps by just clicking on 'Enable'. Although to enable the Archive Page you first have to create the web page that will be going to house the Archive.

Now the Google Sitemap and the Archive Page are ready to be customised from their respective settings pages.
