The efficient way to update?

• I create a pull request to my source code and see the difference
• I don't know another way to update

Hi @thuanowa, yeah I've been asked this question before here. Quick answer is it depends, but github does have some examples in its docs

I got conflict errors while doing that. Look like some major changes have come.
Is there any way to create an efficient update, something like how Hugo Blowfish theme does here?
