+# Readline
+
+The GNU Readline library provides a set of functions for use by applications that allow users to edit command lines as they are typed in. Both Emacs and vi editing modes are available. Readline includes a large number of useful features, including:
+
+- Command line editing and history navigation
+- Customizable key bindings
+- Tab completion support
+- Search capabilities through command history
+- Multi-line editing support
+
+## Features
+
+Readline is used by many command-line applications including bash, gdb, and various scripting languages. It provides a consistent interface for:
+
+- Moving the cursor within the current line
+- Retrieving previous commands from the history list
+- Performing incremental searches of the history list
+- Customizing the behavior through configuration files
+
+## Installation
+
+This package installs the Readline library and header files, allowing other programs to link against it for command line editing capabilities.
+
+## Usage
+
+Applications typically link against libreadline to provide interactive command line interfaces. The library handles all the complex details of terminal control, history management, and user input processing.
+
+## License
+
+Readline is released under the GNU General Public License version 3.
