+### How does the block work?
+
+`figuren-theater/label-printing` is a custom block that uses normal `innerBlocks` to keep the blocks, you are going to add to your label.
+
+To preview the block in the editor and also to render it on the front-end, it uses a hidden, second block called `figuren-theater/label-proxy`. This is a lightweight version of a reusable block, that only works within one post, and not across multiples.
+
+Depending on your selected **pre-defined label** the `…/label-proxy` block will be duplicated as often as the dimensions of the selected label allow. In other words, your label will be fitted into an A4 print-template as often as possible.
