Hello XWIKI developers: My name is Oussema Hidri and I am software engineer student. For GSoC I am interested about the http://dev.xwiki.org/xwiki/bin/view/ GoogleSummerOfCode/RedPenIntegration2017. Few days ago I discussed with one of the members in IRC and he advised me to download and install both XWIKI and RedPen, understand them and write a proposal to you =) I did that and I read the documentations, and as I understood the project is about making an extension that involves validating the content entered by the user. What should be my next step be? Should I start writing my proposal, or send Pull Requests to the JIRA issues? With Love, Oussema Hidri.
