### Feature-pack metadata (feature-pack.xml)

Generally, feature-pack metadata contains the following information:

* *Feature-pack location* - string expression that indicates how to resolve the feature-pack artifact from a remote repository and how it can be identified among other feature-packs;

* _(optional)_ *dependencies* -  dependencies on other feature-packs.

* _(optional)_ *configuration* -  the default configurations of the product (there could be more than one default configuration);

* _(optional)_ *default packages* - names of the packages that are installed by default.

* _(optional)_ *plugins* - various provisioning plugins.

Here is an illustration of how it may look like in a `feature-pack.xml` file:

[source,xml]

    </plugins>
