  **Note:** If you want to push more than a single file, but not the entire contents of a directory, consider using a `.cfignore` file to tell `cf push` what to exclude.
  
  ## <a id='precedence'></a>Precedence Between Manifests, Command-line Options, and Existing Values ##
  
  You can set application attributes using either a manifest or `cf push` command-line options. When you push an application for the first time, `cf` applies default values to attributes that you do not set. On subsequent pushes, you can use command-line options, or manifests, or both.
  
  Between one push and another, attribute values can change in other ways. For example, the `cf scale` command changes the number of instances. The attribute values right before you push represent the cumulative result of defaults, manifest settings, and command-line options, applied up to that point. You can think of them as the values that exist at that moment, or just existing values.
  
  Whenever you push an application, `cf` follows rules of precedence when setting attribute values:
  
  * Manifests override existing values.
  * Command-line options override manifests.
  
  Think of manifests as just another input to `cf push`, to be combined with command-line options and existing values.
  
  ## <a id='optional-attributes'></a>Optional Attributes ##
  
  This section explains how to describe optional application attributes in manifests. Each of these attributes can also be specified by a command-line option. Command-line options override the manifest, except in the case of the `path` attribute, as explained [below](#path).
