+# scaleway_baremetal_os
+
+Gets information about a baremetal operating system.
+For more information, see [the documentation](https://developers.scaleway.com/en/products/baremetal/api).
+
+## Example Usage
+
+```hcl
+# Get info by os name and version
+data "scaleway_baremetal_os" "by_name" {
+  name = "Ubuntu"
+  version = "20.04"
+}
+
+# Get info by os id
+data "scaleway_baremetal_os" "by_id" {
+  os_id = "03b7f4ba-a6a1-4305-984e-b54fafbf1681"
+}
+```
+
+## Argument Reference
+
+- `name` - (Optional) The os name. Only one of `name` and `os_id` should be specified.
+- `version` - (Optional) The os version.
+- `os_id` - (Optional) The operating system id. Only one of `name` and `os_id` should be specified.
+- `zone` - (Defaults to [provider](../index.md#zone) `zone`) The [zone](../guides/regions_and_zones.md#zones) in which the os exists.
