Builder name **** not registered or available through entry point

[banifabio]

Are the changes to Makefile still valid?
Because I think Sphinx changed his Makefile.

To me Add link/Test links, Internalhtml and Livehtml don't work:

>>> make link
Running Sphinx v5.0.2

Sphinx error:
Builder name link not registered or available through entry point

Also I use Windows10 and I have make.bat, you don't. Should I change something there?

Or maybe in conf.py?

Here more details or you can ask me because I'm not sure what can be useful.

Thank you

Btw, good guide!
