# NOOP! framework - Module "yaml" - Installation
* YAML is not an integrated component of PHP and exists only in libraries.
* NOOP uses `spyc` to handle YAML data.
  You can find the library here: https://github.com/cisco211/spyc
* The module is either already available as a `GIT submodule`
  under `module/yaml/spyc`,
  or must be downloaded manually and unpacked in the specified path.
  NOOP tries to load the `Spyc.php` from the `spyc` directory.
* If this works, the value of the constant `MODULE_YAML_FEATURE_SPYC`
  is set to `true`.
  The constant can be used to programmatically find out
  whether `spyc` is available or not.
