Thank you @eladrion for the PR, as you have noticed, I don't have much time to spend on the project nowadays. I updated my contact info, and I would suggest updating the readme team and the following sections. I would suggest removing the team section, as it is quite dynamic to keep track of, and we have pom and .cff files for that. In addition, if Anna-Lena approves, I would suggest adding her email as the main point of contact instead of mine (or few people from the team, not sure how you want to handle that).
