+# Supported Libraries
+
+Pyccel supports a limited subset of the libraries available in Python.
+
+Currently we fully support:
+-   `math`
+-   `cmath`
+
+We additionally have support for the specified functions from the following libraries:
+-   `itertools` : `product`
+-   `numpy` : See [NumPy functions](./numpy-functions.md).
+-   `scipy` : `constants.pi`
+-   `sys` : `exit`
+
+If you need support for a library which is not mentioned here, please open a [discussion](https://github.com/pyccel/pyccel/discussions/categories/ideas) and we will investigate whether this can be added simply.
