+## Other General notes
+Follow the previously mentioned notes as a baseline, and then also consider these additional notes:
+- Certain packages are a bit weird, like Java and Python. Make sure to check existing examples, but especially note the following:
+  - Use py3.x-supported-y packages whenever possible
+  - Use a modern and supported JVM/JDK version (making sure to pick the right packages as well) and loading the environment variables properly
+  - Avoid using obsolete package versions
+- It is worthwhile to search for similar packages to use as working examples over generating something entirely new.
