Bitbucket erpnext repository

Hi All,
Can Someone Please tell me if I want to add a respository of a site (i.e. the code ) to Bitbucket which folder exactly should I add (i.e. frappe-bench/sites/sitename folder or frappe-bench/apps/appname folder as I have installed erpnext app on a site and customized it little bit want to access it on other machine).
Looking forward for your response !

Each folder in the frappe-bench/apps directory is a git repo. If you changed the code in frappe-bench/apps/erpnext you can push it to your bitbucket remote from there.

Thank you @netchampfaris
