Hey everyone, This is Rishabh Kumar Singh, a first-year undergrad student at JIIT-Noida, India. I am highly interested in contributing to XWiki for my first year of GSoC’21. But I am a little confused about that the solution is to be needed for website or desktop app.
You should start by looking at what XWiki exactly is, and it will become much more clear. See https://dev.xwiki.org/xwiki/bin/view/GoogleSummerOfCode/Guidelines.
