It's pretty good. The problem is that the link to that page doesn't exist anywhere. You
need to put it among the all the links in the "various pieces" stuff at the top of the
home page of the Google Group. You also need to put it somewhere on
downloadhelper.net.
The page is there but there are no links on the web site to that page. The web site
points you off to pages where you can find links to install the extension, but it's a
wild goose chase to find pages discussing the CoApp. People have to use the links on the
home page of the Google Group or they have to simply do web searches to find it. (And
that's only the tip of the iceberg of what needs to be fixed on
downloadhelper.net.)
The "More details" link towards the bottom of the page takes you to the README.md page on
Github. The README.md page needs a little tightening up. You need to clearly mark when
a section is referring to Linux issues & when it is referring to other platforms. For
example, if I am not mistaken (I know nothing about Linux beyond its name), all that talk
about Flatpak & Snap is for Linux only. That is not clearly stated. In addition, the
examples of invoking vdhcoapp.exe appear to be Linuxy. In fact, most of the page appears
to be directed towards Linux users & that is not particularly clear. But under Windows,
you can also execute the CoApp at the command line. It doesn't do anything & you have to
Ctrl+c out of it, something you should explain there. But vdhcoapp --help and vdhcoapp
--version could be very handy commands for a Windows user to know about. You should
document those. It is also necessary to tell Windows users that they have to cd to the
right directory. By that I mean you have to name it explicitly in whatever documentation
you put in the README.md.
Also, Paul, please get in the habit of deleting all quoted material from your posts
before you post. I don't know if you're coming on the web site & clicking Reply all, or
using the GMail interface, or some other technique. But your posts contain wholesale
quoting of previous posts. This is wasteful & rather annoying. Please click the 3 dots
to expand the stealth quoted garbage & delete it before you even compose your posts.
