+Config
+======
+
+HTTPie provides a simple configuration file containing a JSON
+object with the following keys:
+
+=========================     =================================================
+``__version__``               HTTPie automatically sets this to its version.
+                              Do not change.
+
+``implicit_content_type``     A ``String`` specifying the implicit content type
+                              for request data. The default value for this
+                              option is ``json`` and can be changed to
+                              ``form``.
+
+``default_options``           An ``Array`` (by default empty) of options
+                              that should be applied to every request.
+=========================     =================================================
+
+The default location is ``~/.httpie/config.json``
+(``%APPDATA%\httpie\config.json`` on Windows).
+
+The config directory location can be changed by setting the
+``HTTPIE_CONFIG_DIR`` environment variable.
