 # Twine
 
-Twine is a command line tool for managing your strings and their translations. These strings are all stored in a master text file and then Twine uses this file to import and export strings in a variety of file types, including iOS and Mac OS X `.strings` files as well as Android `.xml` files. This allows individuals and companies to easily share strings across multiple projects, as well as export strings in any format the user wants.
