 ## Development Info
+- Add a pre-commit hook for autopep8 formatting:
+    - wget https://raw.githubusercontent.com/chibiegg/git-autopep8/master/pre-commit -O .git/hooks/pre-commit
+    - chmod +x .git/hooks/pre-commit
 - Tests should be runnable also on cloud. 
   The setup should be seperated from the test logic.
   When running tests on cloud dependencies will be started ahead and probably passed in by a URL.
