I think I might have a mistake... : pushing directly into main branch (freebsd/freebsd-doc in GitHub)

Hello, 

I think I might have a mistake. :( 

After pulling request _index.po and _index.adoc files in ko branch of freebsd-doc, I have pushed two files into main branch directly. 

/documentation/content/ko/books/handbook/basics/_index.adoc
/documentation/content/ko/books/handbook/basics/_index.po

I knew that..  I should make a branch for Korean language and pushing my result. And then I should request merge into the main branch. 
But I didn’t know that I have a permission to upload at main branch directly. 
Of course I completed proofreading twice. But I wonder if I twisted all other contributors work.
 
Please check. 
Thank you 

KT, Yoo 

Regards.
