You can use a subdomain of your company's domain for your knowledge base.
The setup process is very simple:
At your domain's DNS provider, add a CNAME record for the subdomain you want to use pointing to d.sova.wiki.
For example, if you're using kb
as your subdomain, the CNAME record will look like this:
kb IN CNAME d.sova.wiki.
Open the knowledge base settings, fill in the custom domain you want to use and save changes:
A SSL certificate for your subdomain will be issued automatically.
If you see a certificate error on first open - just reload the page.
We use Let's Encrypt, if your domain has a CAA record - you'll need to allow letsencrypt.org:
kb IN CAA 0 issue "letsencrypt.org"
kb IN CAA 0 issuewild ";"
