+## branching model
+
+### multi master
+
+- paper with many journals, different paper text
+- one branch per journal
+- carefully **cherry-pick** additions to all masters
+
+### trunk based development
+
+- same paper text
+- different themes for journals
+- journal-themes via sub-module --> make them reusable
+
+## helpful commands
+
+Better diff command for text:
+
+```bash
+git diff -w --ignore-blank-lines --word-diff
+```
