Error installing extension

[3goats]

Hi,

When I try to install this extension I'm getting the following error.

Extension Installation Error
An error occurred installing jupyterlab-tutorial.

Error message:

"jupyterlab-tutorial" is not a valid extension:
No `jupyterlab` key

I'm getting the same error in a cleanly built docker image.

Hi, this package is still under development and hasn't been fully tested. However I have a working example of using this within another project and plan to update the documentation to help anyone who is interested in trying it out.
