+This repository represents the BusVoodoo CI (WIP), which consists of:
+
+- compiling firmware on 4 Linux distros via Docker
+
+- Flashing all firmwares to a BusVoodoo device
+
+- Running E2E tests via busvoodoo_e2e_test.py script,
+  which uses pyserial to communicate with the BusVoodoo:
+
+![buusvoodoo_e2e_tests console log](https://boddenberg.it/busvoodoo/busvoodoo_e2e_example.png)
+
+
+- Additionally a testboard (Arduino based) can also be used to test the
+  BusVoodoo's 'self-test' functionality. (a analog multiplexer is
+  necessary to run the self-test.)
+
+- Wrapping all above mentions steps in a Jenkins JobDSL Pipeline
+  and execute them every night if a code change has been introduced.
