To install this patch, ideally you just need to double-click the included
install.exe, which attempts to automatically locate Hatsuyuki Sakura install and
copy the files into the correct directory.

If the automated installer doesn't do anything or fails to locate the install,
you may copy the files over manually.

Manual install instructions in case the installer doesn't work
--------------------------------------------------------------

1. locating the install
-----------------------

Launch the Steam client, go to Library, select Hatsuyuki Sakura, press the gear icon (top right, below the banner) and select Manage > Browse local files.

2. copying the files
--------------------

Copy the contents of "archives" directory (not the directory itself) into 
the game install directory.

config.json is configuration for the patch installer and isn't necessary to
copy, but copying it doesn't cause any harm either.
