how would I proceed with adding these DNS records?

[WCE Administrator]

This domain name is using third party DNS, please contact your DNS provider to add the following records:
mail.hexahedronstudios.com IN CNAME 0 oxwebmail.registrar-servers.com.
hexahedronstudios.com IN MX 10 oxmail1.registrar-servers.com.
hexahedronstudios.com IN TXT 0 v=spf1 includex.registrar-servers.com ~all
hexahedronstudios.com IN MX 10 oxmail2.registrar-servers.com.

So, long story short: I don't quite know how to proceed with this, I am not exactly a skilled webmaster :/

Assuming that you own the domain and that it is hosted on x10,

Go into the x10portal and if you are using the BASIC control panel, switch to cPanel x3 by clicking on the switching button on the top right, then once you have the advanced panel, go down and find "Advanced DNS Zone Editor" and add the DNS entries as show above.

Ah, thank you, I will try that ^^
(yes, I do indeed own the domain. There's a basic control panel? I didn't know (cPanel is nice so I don't mind))

UPDATE: I can't seem to add them, I just get this error

Error

Failed to fetch zone file for hexahedronstudios.com

UPDATE2: Resetting the zone file worked since it created one, will this cause any issues?

The only issue it would possibly create to do so is you'd need to re-add any custom settings you had previously.

Ah yes, I realized that but it isn't an issue as I didn't have any custom settings (let alone a DNS zone file in the first place, it was created when I "reset" the settings)
