+# KCompletion
+
+Powerful completion framework, including completion-enabled lineedit and combobox.
+
+## Introduction
+
+When typing filenames, email addresses and other text where the user often wants
+to select from existing data (including what they previously typed) rather than
+enter anything wholly original, users often find it helpful if they only need to
+type the first few characters, and then have the application offer them a set of
+choices or attempt to finish off what they were typing. Email clients, shells
+and "open file" dialogs often provide this functionality.
+
+This framework helps implement this in Qt-based applications. You can use one of
+the completion-ready widgets provided by this framework, or integrate it into
+your application's other widgets directly.
+
+## Usage
+
+The easiest way to get started is to use a KComboBox, KHistoryComboBox or
+KLineEdit. If you want to integrate completion into other parts of the user
+interface, you can use KCompletion to manage and select the possible
+completions.
