I create my first magento extension .In that extension we replace core edit.phtml in checkout module by custom edit.phtml. It works properly in my localhost. I have some following question:-
1)can i make extension in localhost that i upload in magento store.
2)I have some little bit info about it may also non approved by magento team.so which precaution should i take during creating extension.
3)magento team should check code during approval process?
4)i used magento version 18.104.22.168.
Please suggest something... Thanks,
