The recommended way to install this plugin is to merge the code directory with
the Magento 1 code tree. This means copying each file and directory to its
corresponding location in the Magento 1 codebase. Using a tool such as
`modman` is not recommended, as the latest version of Magento 1 does not
allow symlinks by default.
A possible set of commands on a Unix-system is:
rsync -a path/to/magento/app/ path/to/plugin/app/ rsync -a path/to/magento/js/ path/to/plugin/js/
Beware of the trailing slashes, and try to make a backup of the store before
this operation in case something goes wrong (this is the extent of the plugin
system of Magento 1).
If you clear the cache in the Magento 1 Admin page, by going to System->Cache management->Flush Magento Cache, the plugin should appear as a new button in the top bar.
By clicking on the button in the top bar, you go to the plugin settings
in the global settings menu. There are a few details here that need to be filled in.
