-## Get cool-retro-term
-You can either build cool-retro-term yourself (see below) or walk the easy way and install one of these packages:
+## Install
 
-Fedora has the `cool-retro-term` in the offcial repositories. All you have to do is `sudo dnf install cool-retro-term`.
+If you want to get a hold of the latest version, just go to the Releases page and grab the latest AppImage (Linux) or dmg (macOS).
 
-Users of openSUSE can grab a package from [Open Build Service](http://software.opensuse.org/package/cool-retro-term).
+Alternatively, most distributions such as Ubuntu, Fedora or Arch already package cool-retro-term in their official repositories.
 
-Arch users can install this [package](https://aur.archlinux.org/packages/cool-retro-term-git/) directly via the [AUR](https://aur.archlinux.org):
+## Building
 
-    yaourt -S aur/cool-retro-term-git
-
-or use:
-
-    pacman -S cool-retro-term
-
-to install precompiled from community repository.
-
-Gentoo users can now install the second release "1.0.1" from a 3rd-party repository preferably via layman:
-
-    USE="git" emerge app-portage/layman
-    wget https://www.gerczei.eu/files/gerczei.xml -O /etc/layman/overlays/gerczei.xml
-    layman -f -a qt -a gerczei # those who've added the repo before 27/08/17 should remove, update and add it again as its source has changed
-    ACCEPT_KEYWORDS="~*" emerge =x11-terms/cool-retro-term-1.0.1::gerczei
-
-The live ebuild (version 9999-r1) tracking the bleeding-edge WIP codebase also remains available.
-
-A word of warning: USE flags and keywords are to be added to portage's configuration files and every emerge operation should be executed with '-p' (short option for --pretend) appended to the command line first as per best practice!
-
-Ubuntu users of 14.04 LTS (Trusty) up to 15.10 (Wily) can use [this PPA](https://launchpad.net/~bugs-launchpad-net-falkensweb).
-
-Ubuntu 17.10 can use [this PPA](https://launchpad.net/%7Evantuz/+archive/ubuntu/cool-retro-term)
-
-macOS users can grab the latest dmg from the release page: https://github.com/Swordfish90/cool-retro-term/releases

-
-# Build it
-cd cool-retro-term
