+### Logo customization
+
+The `Makefile` supports generating the case with different logos. For now, the
+only parts that are customizable with logos are `MainCase/MainCase` and
+`MainCase/MainCaseLid`. Please check the instructions in
+[`logo/README.md`](./logo/README.md) for creating your own logo version.
