 You can install Mitiq support for these frontends by specifying them during installation, 
 as optional extras, along with the main package.
 To install Mitiq with one or more frontends, you can specify each frontend in square brackets as part of the installation command. 
 
-For example, 
+For example,
 to install Mitiq with support for Qiskit and Qibo:
 ```bash
 pip install mitiq[qiskit,qibo]
