# Using a Namespace in or from a Managed Package

Always use the complete namespace when referencing items from a managed package, or when creating code that you intend to distribute in your own managed packages.

Another component or application can reference a component by adding `<pkgNamespace:pkgComponent>` in its markup. For example, let’s look at a package that contains the `helloWorld` component in the docsample namespace. Another component can reference the component from the package by adding `<docsample:helloWorld />` in its markup.
