Hi @4k4 Sorry I have tried to create an entity and bundles but I never am able to create something complete? What commands do I use to create an entity and bundle so that I can add fields to it?

Nice one thank you, that indeed makes a lot of sense, I shall give that a go

I suppose I just want a one off custom block and don't necessarily want it to be a replicable thing. I have quite a few use cases where this would make more sense. Also it is better for pushing up the code using versioning

Thanks, I think I have got this far but I would like to be able to add an image field to the block and then to print a responsive image style version of this in a block.html.twig file
