mislav · mislav · commit 016df6af1cdb · 2020-09-07T17:06:03.000+02:00
- Move all Linux installation docs to the separate page to eliminate repetition
- Indicate that only Ubuntu 20.04 is supported for apt-add-repository method
- Pull openSUSE/SUSE out of the "unofficial" section since it refers to
  downloading our official packages
- Point out manual installation methods as well

 # Installing gh on Linux
 
-The core, paid developers of `gh` officially support a `.deb` repository and a `.rpm` repository. We
-primarily test against Ubuntu and Fedora but do our best to support other distros that can work with
-our repositories. We focus on support for `amd64` and `i386` architectures.
+Packages downloaded from https://cli.github.com or from https://github.com/cli/cli/releases
+are considered official binaries. We focus on a couple of popular Linux distros and
+the following CPU architectures: `386`, `amd64`, `arm64`.
 
-All other combinations of distro, packaging, or architecture should be considered community
-supported.
+Other sources for installation are community-maintained and thus might lag behind
+our release schedule.
