Comment 2 for bug 1957945

The R4 Installation Guides are archived in the R5 doc branch.
It is true that the internal links within the R4 installation guides are broken.
However, R4 is in EOL state and the docs are no longer maintained.

Please refer to the most up-to-date Installation Guides in the latest release here:
https://docs.starlingx.io/deploy_install_guides/r6_release/index.html

Or if you need R5 docs specifically, use the R5 Distributed Cloud install guide here:
https://docs.starlingx.io/r/stx.5.0/deploy_install_guides/r5_release/distributed_cloud/index.html
