Using VS Code
**************
Next you login to the Beagle from your host computer.
Here you have a choice. If you want a graphical approach,
choose the ``VS Code`` tab. If you want a command line
and your host is a Mac, take the ``ssh (Mac)`` tab. If you
are running Linux on your host,
take the ``ssh (Linux)`` tab. Finally take the
``putty (Windows)`` tab for command line from Windows.
.. important:: If VS code is not installed on your board please skip this section and refer
to next section on how to login and run the code via command line.
