[arch-general] Wiki edition

Hi guys. I have a Brazilian Lenovo Ideapad 330S-14IKB laptop and would like to add it to Wiki. I know there is a Lenovo 330S page, but it shows a different version. How can I proceed to create a new page or change the current one? Sorry to ask this, but I don't have much experience on Wikis. Thanks for your help. *Beste Grüße* *Tomás Schertel*
