 ### Getting the snippet contents
 
 The `getLines()` method returns an array of `SnippetLine` instances.  The keys of the resulting array are the line numbers.
 
-The `SnippetLine` instances may be cast to strings to display the value.
+The `SnippetLine` instances may be cast to strings to display the value.  When working with `SnippetLine` instances, use `isSelected()` to determine if the line was selected using either the `surroundingLine()` or `surroundingLines()` method on the `CodeSnippet` instance.

-use Permafrost\CodeSnippets\CodeSnippet;
+To get the value of a `SnippetLine`, use the `value()` method or cast the object to a string.
