In order to publish your site, you must first decide a domain, which is the address of your home page. If you have your own domain, you can also use it. If not, you can easily use the STUDIO subdomain.

Click "Publish" in the top right corner of the editor or "Publish Settings" on the dashboard to open the project's Publish Settings panel.
Publishing in subdomains
With STUDIO's FREE plan, you can publish your site as a subdomain of studio.site. Specify the part of XXXXXXX.studio.site for each site.
Enter the string you want to make a subdomain, and if available, a "Save" button will appear to save and publish.
Publishing with custom domain
If you want to publish your site on your own domain that does not include studio.site, the following is required
