+We're excited to announce the launch of the PyHC Documentation Hub, now available at **[pyhc.org/pyhc-docs](https://pyhc.org/pyhc-docs)**. This centralized resource simplifies how you search across documentation for all PyHC packages that use Read The Docs. No more switching between dozens of disparate package websites to find the information you need. The Hub not only links all packages together in one convenient place but also provides a powerful search interface that organizes results by package for easy navigation. Find documentation faster than ever—we hope you find it useful. _**[Try it out today!](https://pyhc.org/pyhc-docs)**_
