Start The Demo#

Tip

Right click and "open image in new tab" to see large images

After the codespaces has started, the post creation script should begin. This will install everything and will take a few moments.

When the script has completed, a success message will briefly be displayed (it is so quick you'll probably miss it) and an empty terminal window will be shown.
