# Sphinx proof
This extensions provides an easy way to add proofs, theorem, axioms and much more to your book. It is created by the Executable Books team and is [documented here](https://sphinx-proof.readthedocs.io/en/latest/).
TeachBooks has made some small modifications to the original extension, such that it works well with translated books; this modified version is located in the repository [github.com/TeachBooks/sphinx-proof](https://github.com/TeachBooks/sphinx-proof).
## What does it do?
This extension defines proofs, theorems, axioms and other similar concepts as new admonition types:
````{prf:example}
:label: my-example
Next, we shut down randomness in demand and assume that the demand shock
$\nu_t$ follows a deterministic path:
```{math}
\nu_t = \alpha + \rho \nu_{t-1}
```
Again, we’ll compute and display outcomes in some figures
```python
ex2 = SmoothingExample(C2=[[0], [0]])
x0 = [0, 1, 0]
ex2.simulate(x0)
```
````
More information can be found in the [official documentation](https://sphinx-proof.readthedocs.io/en/latest/index.html). It can be [configured in combination the TeachBooks extension to include examples with executable code and visuals](../_git/github.com_TeachBooks_sphinx-code-examples/main/MANUAL.ipynb).
