+> 🚧 **Under construction** 🚧
+> This repository is a development version under construction. The list of resources is just a small set for debugging and development purposes.
+> For now, we focus on developing features that we think could be useful for the community (e.g., `BibTex`-first structure).
+> Then, we will evaluate whether this project has the potential to be useful for the community in addition to existing lists
+> that are specifically designated to *simulation-based inference* and not *amortized inference* (which doesn't need to be simulation-based).
+> Once we figure out the direction and deem the project potentially useful for the community, we'll launch and add an extensive set of resources 
+> -- hopefully with the help of many awesome people from the community 🧡
