What I was talking about is a page with some basic installation
instructions for all the major distros, not a complete Wiki, please
allow me to explain my thinking.
Linux users typically the first
thing they will look for when they want to install a new piece of
software, is how they can install it with their package manager rather
than from where they can download a binary. So, if the JavaScript
detects that the user is running Linux,
it could simply replace the
"Download" with an "Install" button which will link to the "Install"
page. The "Install" page doesn't need to have detailed instructions on
how to setup and configure everything, just a couple of commands for
each distro that can easily being copied and pasted in order to install
the software.
Windows users look for a link to download the
binary, Linux users users usually look for the command that they can use
to install it. Personally, as a Linux user I love when websites
implement this kind of functionality instead of simply putting a
"Download" button to a deb file, and I'm pretty sure I'm not the only
one.
