+# Inspect annotation
+
+The inspect annotation can be used to request the baremetal operator to (re-)inspect a `Ready` BareMetalHost.
+This is useful in case there were hardware changes for example.
+Note that it is only possible to do this when BareMetalHost is in `Ready` state.
+If an inspection request is made while BareMetalHost is any other state than Ready, the request will be ignored.
+
+To request a new inspection, simply annotating the host with `inspect.metal3.io` is enough.
+Once inspection is requested, you should see the BMH in inspecting state until inspection is completed, and by the end of inspection the `inspect.metal3.io` annotation will be removed automatically.
+
+Here is an example:
+
+```yaml
+apiVersion: metal3.io/v1alpha1
+kind: BareMetalHost
+metadata:
+  name: example
+  annotations:
+    # The inspect annotation with no value
+    inspect.metal3.io: ""
+spec:
+  online: true
+  bootMACAddress: 00:8a:b6:8e:ac:b8
+  bootMode: legacy
+  bmc:
+    address: ipmi://192.168.111.1:6230
+    credentialsName: example-bmc-secret
+...
+```
+
+Why is this needed?
+
+- For re-inspecting BareMetalHosts after hardware changes.
+
+Caveats:
+
+- It is only possible to inspect a BareMetalHost when it is in `Ready` state.
+
+Note: For other use cases, like disabling inspection or providing externally gathered inspection data, see [external inspection](./external_inspection.md).
