+## `image-builder describe`
+
+The `describe` command outputs structured information about an image without building it. It lists the packages that would be used to build the images and the partition tables.
+
+```console
+$ image-builder describe minimal-raw
+@WARNING - the output format is not stable yet and may change
+distro: fedora-43
+type: minimal-raw-zst
+arch: x86_64
+os_version: "43"
+bootmode: uefi
+partition_type: gpt
+default_filename: disk.raw.zst

+      - shim-x64
+    exclude:
+      - dracut-config-rescue
+      - firewalld
+```
+
+By default the `describe` command uses the same distribution and version as the host system, you can pass another distribution and version with the `--distro` argument:
+
+```console
+$ image-builder describe --distro fedora-43 minimal-raw
+# ... output ...
+```
+
+When passed `--arch` `image-builder` will show the description for that architecture:
+
+```console
+$ image-builder describe --arch aarch64 minimal-raw
+# ... output ...
+```
+
 # Blueprints
 
 Images can be customized with [blueprints](https://osbuild.org/docs/user-guide/blueprint-reference). For example we could build the `qcow2` we built above with some customizations applied.
