Hey, guy
Here are the steps required to brand name servers for Reseller hosting or any shared hosting.

1)Child name servers.

Name Servers which are registered under your domain name are called Child Name Servers. After you must register Name Servers, you can use them as Name Servers to register other domain names.Child Name Servers can only be registered by the owner of the domain that they are registered.For example;A Child Name Server ns1.clientlix.com can only be registered by the owner of clientlix.com.

Login to the account of your domain registered and update the child name server

Ex.- 

ns1.domainprovide.com->Server IP address
ns2.domainprovide.com->Server IP address.

2)A records.

A Records are the most basic type of DNS record and are used to point a domain or subdomain to an IP address. Assigning a value to an A record is as simple as providing your DNS management panel with an IP address to where the domain or subdomain should point and a TTL

Ex.- 

ns1.domainprovide.com IN A Server IP address
ns2.domainprovide.com IN A Server IP address.

The A records need to be added in the cPanel zone editor option.

3) Modify nameservers

Change the nameservers of the domain to ns1.domainprovide.com and ns2.domainprovide.com

Wait for propagation timeframe of 24-48 hours

Hope you guys understand this
