Everyone can contribute! Learn DevOps and Cloud Native in our cafe ☕

Our website and blog came from the first iteration where we started with a Google doc, and then later moved to GitLab projects, issues and this website deployed with pages. This blog post summarizes everything which happened thus far and adds the archive for older Kaeffchens as well. The meeting notes are untouched and provide the raw impressions, typos included.

Everything in this blog post covers our German Kaeffchen. We made the decision to chat in German/Austrian and document the notes in English. Future iterations will introduce an English and maybe Spanish ☕ chat too.

You can follow the Kaeffchen YouTube Playlist and dive deeper below.
