"-r" flag described in the docs no longer works

[Valeriu Dorin Chiș]

As title suggests, the wiki references the "-r" flag used for rotating the output. The flag was removed.
Would it be possible to add an example on how to achieve output rotation without the flag?

Hi @vchis,
Sadly, GitHub does not allow to send PRs for the wiki part.
The -r option has been removed as Cage now support wlr-output-management protocol. With tool using this protocol such as wlr-randr or kanshi, you can play with the transform parameter.
For example (adjust with the real name of your output):
$ wlr-randr --output HDMI-A-1 --transform 90
