 ## Examples
 
 - [Simple](simple/demo.ipynb): A basic example of using Tesseract-JAX with a simple vector addition task. It demonstrates how to build a Tesseract and execute it within JAX.
-- [CFD](cfd/demo.ipynb): A more complex example demonstrating how to use Tesseract-JAX to differentiate through a computational fluid dynamics (CFD) simulation Tesseract.
+- [CFD](cfd/demo.ipynb): A more complex example demonstrating how to use Tesseract-JAX to differentiate through a computational fluid dynamics (CFD) simulation in an optimization context.
