+## Formatting
+
+You can convert your compiled circuit into its textual representation by converting it to string:
+
+<!--pytest-codeblocks:skip-->
+```python
+str(circuit)
+```
+
+If you just want to see the output on your terminal, you can directly print it as well:
+
+<!--pytest-codeblocks:skip-->
+```python
+print(circuit)

-# Format and Draw
-
-Sometimes, it can be useful to format or draw circuits. We provide methods to just do that.
-
-## Formatting
-
-You can convert your compiled circuit into its textual representation by converting it to string:
-
-<!--pytest-codeblocks:skip-->
-```python
-str(circuit)
-```
-
-If you just want to see the output on your terminal, you can directly print it as well:
-
-<!--pytest-codeblocks:skip-->
-```python
-print(circuit)
-```
-
-## Drawing
-
-{% hint style="danger" %}
-Drawing functionality requires the installation of the package with a full feature set. See the Installation section to learn how to do that.
-{% endhint %}
-
-You can use the `draw` method of your compiled circuit to draw it:
-
-<!--pytest-codeblocks:skip-->
-```python
-drawing = circuit.draw()
-```
-
-This method will draw the circuit on a temporary PNG file and return the path to this file.
-
-You can show the drawing in a Jupyter notebook, like this:
-
-<!--pytest-codeblocks:skip-->
-```python
-from PIL import Image
-drawing = Image.open(circuit.draw())
-drawing.show()
-drawing.close()
-```
-
-Or, you can use the `show` option of the `draw` method to show the drawing with matplotlib.
-
-<!--pytest-codeblocks:skip-->
-```python
-circuit.draw(show=True)
-```
-
-{% hint style="danger" %}
-Beware that this will clear the matplotlib plots you have.
-{% endhint %}
-
-Lastly, you can save the drawing to a specific path:
-
-<!--pytest-codeblocks:skip-->
-```python
-destination = "/tmp/path/of/your/choice.png"
-drawing = circuit.draw(save_to=destination)
-assert drawing == destination
-```
