-## Brain Dynamics Programming Ecosystem
-
-We are building an ecosystem for bain dynamics programming (BDP), evolving from our previously experimental [BrainPy package](https://github.com/brainpy/BrainPy).
-
-The BDP ecosystem is a collection of tools, libraries, and frameworks that can be used to build brain dynamics models and applications.
-
-The BDP ecosystem is designed to be modular, so you can use as much or as little of it as you need.
-
-The details for this ecosystem please see: https://ecosystem-for-brain-dynamics.readthedocs.io/
-
-We welcome contributions from the community, so if you have an idea for a new tool or library, please let us know! Please email us at: <chao.brain@qq.com>.
