While most of the content will be introduced on the day, it is likely very beneficial to follow some topics from the recent EESSI webinar series relevant to the hackathon:
- Introduction to EESSI (April 2026)
- Introduction to EasyBuild (May 2026): slides - recording
Some familiarity with Git is useful, as is some experience with building and/or installing software packages.
For posting questions or comments during the event, we strongly prefer that you post them
in the #hackathon channel in the EESSI Slack (direct link to that channel).
