Can someone please help me how to upload mangas in this site?

link in the thing you want to upload on the site in the report area, you know the tiny flag that shows up on the side when you be reading, that one

Do we need a software to do this?

I don't know... Everything ! lol

I really suck at informatic and your tutorial looks to me too fast ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄

So nice of you!
This is better for my comprehension, but still looks like Chinese language to me :'D

This is good to know. If ever I want your help, can I ask you?
I'm an artist, you see, and I'll need someone to help me if I have something to share on manga sites.

Merci beaucoup !
