Right now sympy.org/live redirects to https://www.sympy.org/live/repl/index.html, which appears to be just the internal frame of a jupyterlite shell . It would be better if it redirected to https://www.sympy.org/en/shell.html.
By the way, feel free to move issues around between this repo or the sympy.github.com repo. I don't know which is better for things.
