Hello, I’m Daniel, intern at XWiki SAS, and I’m ready to make my first contribution to an open source project.
Hi Daniel, welcome aboard!
Please check Contributing - XWiki
PS: Make sure to differentiate XWiki SAS (the company) from the XWiki open source project (which has its own governance and is managed independently of the company, see What is the relationship between XWiki SAS and the XWiki open source project? (XWiki.org) ).
