# Kernels

## Add and remove kernels

The IPython kernel is the Python execution backend for Jupyter.

Under **Environments**, choose an environment, and expand its panel. Click **Add kernel** to create an ipykernel for the environment.
This is a necessary step before running code in a Jupyter Notebook using a given environment.

Once "active", click **Remove kernel** to remove the environment's ipykernel from the launcher.
