+            Zammad is a web-based, open source user support/ticketing solution. For Zammad and a database server like PostgreSQL we recommend at least:
+
+            - 2 CPU cores
+            - 4 GB of RAM (+4 GB if you want to run Elasticsearch on the same server)
+            - For optimal performance up to 40 agents:
+            - 4 CPU cores
+            - 6 GB of RAM (+6 GB if you want to run Elasticsearch on the same server)
+

             Zammad is deployed and available.
              IMPORTANT: It will take up to 5 minutes for Zammad to be ready. Before that, you might see a 502 error page.
