|| To stop the '''server''', press '''Ctrl''' and '''C''' keys simultaneously.
|-
|| [Terminal]

Type deactivate and press Enter
|| When the '''virtual environment''' is not in use, we can deactivate it.

To do so, type '''deactivate''' and press '''Enter'''.
|-
|| [Terminal]

Point the shell prompt
|| We can see that, the '''virtual environment '''name disappears from the '''command prompt.'''
|-
|| Switch to Slide

Slide: Delete the virtual environment

|| If the '''virtual environment''' is no longer needed, we can delete it.

This is done by deleting its '''directory'''.

The command is '''rm <space> hyphen rf <space> myapp underscore env'''
|-
|| Only narration
|| For now, we will not delete.

We will keep the '''virtual environment '''for creating the '''Django project '''in the upcoming tutorials.
|-
