 ### Added
 
+- Commands to install tkinter on the common Linux distributions, and tkinter and Tktable where
+  they have a Tktable package.
 - Installation docs for more Linux distributions (Kali Linux, Gentoo, Slackware), FreeBSD, OpenBSD,
   NetBSD and conda, with separate pages for Linux and macOS.
 - Links to the GitHub repository on the docs' home page and in the footer of every page.

 pytktable finds it automatically, so you don't need to install Tktable or set `TKTABLE_LIBRARY`.
 You only need tkinter, which the python.org installers for Windows and macOS include. On Linux,
-install your distribution's tkinter package, e.g.:
+install your distribution's tkinter package:
 
-```sh
-sudo apt install python3-tk

-
-on Debian and Ubuntu, or:

-on Fedora. Tktable also needs the X11 library (`libX11`), which every desktop Linux has.

+| Debian, Ubuntu, Linux Mint, Kali Linux | `sudo apt install python3-tk` |

+| Arch Linux, Manjaro | `sudo pacman -S tk` |
+| Gentoo | Python built with the `tk` USE flag |
+
+On RHEL 9 and its rebuilds, `python3` is Python 3.9, older than pytktable requires, so use

+[Testing](https://github.com/nbro/pytktable-binaries/blob/main/docs/testing.md)). Tktable also
