Hello 👋

I’ve posted two examples to the documentation of cereggii on usages for AtomicDict, which was [presented at the 2024 Language Summit](https://pyfound.blogspot.com/2024/06/python-language-summit-2024-free-threading-ecosystems.html).

- [Using `reduce()` for Multithreaded Aggregation](https://dpdani.github.io/cereggii/examples/AtomicDict/reduce/)
- [Using `reduce()` for Averaging](https://dpdani.github.io/cereggii/examples/AtomicDict/reduce-average/)

I think the library is now at a much more usable place than it was back then.  
Any feedback on the library and the examples is very welcome 🙂
