 # CLI11: An introduction
 
-This gitbook is designed to provide an introduction to using the CLI11 library to write your own command line programs. The library is designed to be clean, intuitive, but powerful. There are no requirements beyond C++11 support (and even `<regex>` support not required). It works on Mac, Linux, and Windows, and has 100% test coverage on all three systems. You can simply drop in a single header file (`CLI11.hpp` available in [releases]) to use CLI11 in your own application. Other ways to integrate it into a build system are listed in the [README][].

 ## Triggering Subcommands
 
-Configuration files can be used to trigger subcommands if a subcommand is set to configure.  By default configuration file just set the default values of a subcommand.  But if the `configure()` option is set on a subcommand then the if the subcommand is utilized via a `[subname]` block in the configuration file it will act as if it were called from the command line.  Subsubcommands can be triggered via [subname.subsubname].  Using the `[[subname]]` will be as if the subcommand were triggered multiple times from the command line.  This functionality can allow the configuration file to act as a scripting file.

 For custom configuration files this behavior can be triggered by specifying the parent subcommands in the structure and `++` as the name to open a new subcommand scope and `--` to close it.  These names trigger the different callbacks of configurable subcommands.
