Following previous editions in Stockholm (2015), Trento (2016) and Mallorca (2017), the 2018 edition of the European Einstein Toolkit Workshop was held in Lisbon, IST. The meeting was a success, with participants from all corners of the world. Material from the tutorial sessions and contributed talks is now being made available at the meeting webpage. We will all meet again next year at King's College London!
