Hi @gidden, please clarify for me: I thought we wanted to have the tutorials be part of message-ix-models. Was this decision revised? Should I still set up a docs page etc for tutorials in message-ix-models?

[gidden]

Hey @glatterf42 - good questions. Yes, in reviewing this PR and related work with @ywpratama yesterday, we realized that his add_dac() functionality was more generic and could be applied at a high level repo (similar to add_years() here). That is at least the proposal for now, which we can discuss once the PR is finalized.

So in short, no need to add tutorials page yet to message-ix-models

[gidden]

@glatterf42 and @ywpratama - this PR now has the content added to it that is expected. It would be useful if the two of you could sit down and discuss how to best add relevant tests for this so it can be merged.

@ywpratama there should be already available documentation for how to pass the code quality checks
