+<p>{% trans %}A <em>view</em> is a listing of items on your site; for example, a block showing the most recent comments, a page listing news items, or a list of registered users. The listings can be formatted in a table, grid, list, calendar, RSS feed, and other formats (some output formats may require you to install additional contributed modules).{% endtrans %}</p>
+<h2>{% trans %}What are the components of a view?{% endtrans %}</h2>
+<p>{% trans %}When you first create a view, you will specify what type of <em>base data</em> is being displayed in the view, which cannot be changed. After choosing a base data type, you can edit the following components, which allow you to specify which data to output, in what order, and in what format:{% endtrans %}</p>
