### Validating a single, valid file

    $ ./bin/kubeconform fixtures/valid.yaml
    $ echo $?
    0

### Validating a single invalid file, setting output to json, and printing a summary

    $ ./bin/kubeconform -summary -output json fixtures/invalid.yaml
    {
      "resources": [
        {
          "filename": "fixtures/invalid.yaml",
          "kind": "ReplicationController",
          "version": "v1",
          "status": "INVALID",
          "msg": "Additional property templates is not allowed - Invalid type. Expected: [integer,null], given: string"
        }
      ],
      "summary": {
        "valid": 0,
        "invalid": 1,
        "errors": 0,
        "skipped": 0
      }
    }
    $ echo $?
    1

### Passing manifests via Stdin

    cat fixtures/valid.yaml  | ./bin/kubeconform -summary
    Summary: 1 resource found parsing stdin - Valid: 1, Invalid: 0, Errors: 0 Skipped: 0

### Validating a folder, increasing the number of parallel workers

    $ ./bin/kubeconform -summary -n 16 fixtures
    fixtures/crd_schema.yaml - CustomResourceDefinition trainingjobs.sagemaker.aws.amazon.com failed validation: could not find schema for CustomResourceDefinition
    fixtures/invalid.yaml - ReplicationController bob is invalid: Invalid type. Expected: [integer,null], given: string
    [...]
    Summary: 65 resources found in 34 files - Valid: 55, Invalid: 2, Errors: 8 Skipped: 0
