There are two ways to brand the app to your domain name. By branding we mean that users will see you domain as the source of the installation.
(1) Branding with SUBDOMAIN
a) Log into your website's domain admin panel.
b) Create new record of type "CNAME"
c) Put into "HOST" = your mobsted account name, which you can see in example in BOLD - http://a64hs61c54d-admin.mobsted.com/
d) Set it's "POINT TO" = your mobsted account name - http://a64hs61c54d.mobsted.com/ - WITHOUT the "-admin"
_________
e) Create the second new record of type "CNAME"
f) Put into "HOST" = your mobsted account name WITH THE "-ADMIN" part , which you can see in example in BOLD - http://a64hs61c54d-admin.mobsted.com/
g) Set it's "POINT TO" = your mobsted account name - http://a64hs61c54d-admin.mobsted.com/
ALLOW for about 15 minutes to a couple of hours for the procedure to take effect, as your domain hosting provider needs to update it's records into the world wide web.
