Add explanation for conceptual decisions

[1kastner]

Is there an explanation for what has been included into which docker image? A maybe stupid question for people who have deeper insights in the project: Why don't I have an extension manager on the left side when starting the IDE? I wish the delivered version could be closer to VS code. This would make the transition much easier. Maybe there is a better place for a discussion like this. If so, could a link be added to the README.md? That'd be great! Thanks so much for all the contributions!

@1kastner the extensions view is not yet part of the images since it is a fairly new extension. Note that due to license issues and terms of use, any non-official vscode product is forbidden to use the marketplace, that is why we have created the open-source alternative open-vsx. Until this was created, an extensions view was not possible, but it is now implemented :) We have a pull-request which adds the view to most images:

• add vsx-registry to ci builds #330

If you have additional feedback of what might be nice to include in the readme, I'd suggest giving some feedback to the following pull-request #279 which updates the readme.

Thank you very much for your comment, @vince-fugnitto !

Then I guess we should discuss it in #279 .
