 # QuickIK
 
-Fast inverse kinematics library aimed for both high throughput and low latency.
+QuickIK is a fast inverse kinematics library written in Rust, with Python and C++ bindings.
 
-QuickIK provides high-level APIs for processing consecutive frames (i.e. with warm starts) and multi-threaded batch processing, as well as low-level APIs for more specific use cases (e.g. real-time application). QuickIK is written in Rust but comes with Python and C++ bindings.

 ## For developers
 
+### Toolchain
+
 A series of Python tools are used for development (Python bindings build tools, linting, benchmark plotting, unit testing, etc.). These are provided in a uv-managed environment under [`devtools-pyenv/`](devtools-pyenv/). This environment is unrelated to the QuickIK Python bindings, which lives under [`python/`](python/). The rest of the section assumes you have activated this environment:
 
 ```sh
