+          ## Choosing An Installer for Linux
+
+          The bare binary
+          [`${{ steps.create_script.outputs.repo_name }}`](${{ github.server_url }}/${{ github.repository }}/releases/download/${{ github.ref_name }}/${{ steps.create_script.outputs.repo_name }})
+          should work on all Linux distros. Download it, then run `chmod +x ./${{ steps.create_script.outputs.repo_name }}` as usual.
+
+          The `unknown-linux-gnu` target is preferable for GNU/Linux with glibc version 2.31 or above.
+          In simpler words: `unknown-linux-gnu` is recommended for Arch Linux, Ubuntu 20.04, Debian 11
+          (Bullseye), CentOS 9, RHEL 9, or newer. Older systems should download the `unknown-linux-musl` variant.
+
+          ## Installation Script
+
           A script is provided for downloading and installing the binary.
 
           Install for all users (requires `sudo`):
