 Sometimes, it may be necessary to install a devroot for an architecture or a
 version of Apertis different than that coming pre-installed with the SDK image.
 Since devroots are ospacks specially built each time during the build process,
-installing them can be done separately as described below. Apertis currently
-only builds armhf devroots, but this may change in future.
+installing them can be done separately as described below.

 where:
-- `<release>` is the release version, e.g. `19.03`
-- `<timestamp>` is the version of the image, e.g. `20181206.0`
-- `<arch>` is the architecture, e.g. `armhf`
+- `<release>` is the release, e.g. `v2023`
+- `<version>` is the version of the image, e.g. `v2023.1`
+- `<arch>` is the architecture, e.g. `arm64`
 - `/opt/directory-to-unpack-into` is the directory into which the devroot will
   be installed
 
-Similarly, for the release images, replace the `/daily/<release>/<timestamp>/`
-bit with `/release/<release>/<version>/`, e.g. `/release/18.12/18.12.0/`.
