Marking text in our templates for translation

To get started, we will have to specify the text in our templates that we would like to translate. To ensure text is successfully translated, we will have to not only specify what text needs to be translated, but we will also need to provide a description and a contextual meaning. Below is an example of the changes we would have to make to an <h1> tag to mark the the text for translation, and provide a description and contextual meaning:

<h1 i18n="User welcome|An introduction header for this sample">Hello {{name}}</h1>

We use the pipe (|) to seperate the description (left) and contextual meaning (right).
