 ## Technology choices
 ### Visual Studio Code + Remote Development / Dev Containers
-With VS Code Remote Development, you can use a Docker container as a full-featured development environment. VS Code is going to work **as if it was running locally on the Linux container** I chose to develop on. Other tools offer similar solutions of course (mounting the workspace, hot-reload), but I find the extreme approach of hooking the entire "IDE" into a container quite inspiring.

+To open the dev container:
+- Open the folder in VS Code
+- Reopen in container (popup in bottom right of the window)
+- Find a Java file, hit F5
+- Say yes to Java standard mode (popup in bottom right of the window)
+- After a minute and the Java mode switch, you're in - now you're developing on a 'remote' machine. Move it to the cloud and you've got GitHub CodeSpaces.
