Hi, 

I brought a domain name from third party but not the host server. how do i connect to my squarespace? 

the domain name i brought is www.littlecarsg.sg 

under the remarks, they say squarespace do not support sg. 

i only brought the domain, but not the host. 

what should i do? 

Squarespace cannot host your .sg domain but if you bought your domain with domain hosting, you can connect it to Squarespace by using this guide. If you bought it without domain hosting, you must purchase this and set it up before you can connect it. 

Thank You Paul
