Download the zip archive and unzip it into the plugins.local subdirectory of your Tiny Tiny RSS installation. Note that the directory containing init.php must be named ff_instagram, otherwise the plugin won't be loaded, so you may have to rename it after the unzipping.
After that, the plugin must be enabled in the preferences of Tiny Tiny RSS.
