Flame offline help documentation

Hi everyone,
When I go to Help>Flame Help
It does not load the documentation in firefox as flame is not connected to the internet.

Where can I download and install the entire flame user manual to view offline?

Firefox says
A local version of flame help can be installed from

You must be connected to the internet to perform the download

I clicked on this link on my phone and could not find it.

Also does it need to be downloaded and installed here

Thanks for all the help in advance
