+### Options
+
+```
+      --description string   The description of the suggested size (default "a suggested size")
+  -h, --help                 help for suggest
+      --labels strings       labels to add to the size
+      --machine-id string    Machine id used to create the size suggestion. [required]
+      --name string          The name of the suggested size (default "suggested-size")
+```
+
+### Options inherited from parent commands
+
+```
+      --api-token string       api token to authenticate. Can be specified with METALCTL_API_TOKEN environment variable.
+      --api-url string         api server address. Can be specified with METALCTL_API_URL environment variable.
+  -c, --config string          alternative config file path, (default is ~/.metalctl/config.yaml).
+                               Example config.yaml:
+
+                               ---
+                               apitoken: "alongtoken"
+                               ...
+
+
+      --debug                  debug output
+      --force-color            force colored output even without tty
+      --kubeconfig string      Path to the kube-config to use for authentication and authorization. Is updated by login. Uses default path if not specified.
+      --no-headers             do not print headers of table output format (default print headers)
+  -o, --output-format string   output format (table|wide|markdown|json|yaml|template), wide is a table with more columns. (default "table")
+      --template string        output template for template output-format, go template format.
+                               For property names inspect the output of -o json or -o yaml for reference.
+                               Example for machines:
+
+                               metalctl machine list -o template --template "{{ .id }}:{{ .size.id  }}"
+
+
+      --yes-i-really-mean-it   skips security prompts (which can be dangerous to set blindly because actions can lead to data loss or additional costs)
