INSTALL file need update

[HilebertSpace]

Is your feature request related to a problem? Please describe.
I use Debian GNU/Linux sid. To install MystiQ, I checked the INSTALL file and it suggested that I add additional repositories to install MystiQ.But I checked the Debian repository, which contains the package mystiq.
Describe the solution you'd like
I think the INSTALL file should advise Debian users to install it from the Debian repository.
Describe alternatives you've considered
The installation recommendations for Debian users should be updated:

For Debian Unstable run the following as root:

apt update
apt install mystiq

For Debian Testing run the following as root:

apt update
apt install mystiq

For Debian Stable (10) run the following as root:

echo 'deb http://deb.debian.org/debian buster-backports main contrib non-free' > /etc/apt/sources.list.d/buster-backports.list
apt update
apt -t buster-backports install mystiq

Additional context
None.

and for the part of Arch Linux, now we do not have to edit file. we just install it from AUR - mystiq
