+# Github Workflows
+
+## Overview
+
+![gh_actions.drawio.png](gh_actions.drawio.png)
+
+## PR verification
+
+To ensure a stable main branch we verify PRs once they are created/updated and again when they are accepted and enter the merge queue. Therefore each verification workflow needs to have both ``pull_request`` and ``merge_group`` set in the trigger conditions.
+Additionally all jobs for the merge queue have to be explicitly added in the [otterdog configuration](https://github.com/eclipse-openbsw/.eclipsefdn/blob/main/otterdog/eclipse-openbsw.jsonnet).
+
+## General guidelines
+
+1. Don't waste compute time.
+2. Each job should have a specific purpose.
+3. Each artifact produced should make sense on it's own.
+4. Don't rely on a different job running afterwards. Keep cohesion low.
+5. Each job should have a unique name.
