I know this may seem very basic, but I'm brand new to this. How can I go about installing the GeoIP plugin (https://github.com/Torann/laravel-geoip/tree/0.1.1) for octobercms. Further, what is the process to install any plugin from Github?

First, you must use the master branch of your plugin (GeoIp).

Second, I don't recommand using Laravel plugin, because its require some config file, that cannot be used from plugin.

As I said, you should use a solution without any depencies, or only Composer. Try with geoip/geoip it should work. Add it to your composer, and then run the plugin.

Which composer file should I be adding it to. Last time I tried this (previous post), it broke the entire OctoberCMS installation, so I don't want to go through that again. There is no composer.json in my root directory of a fresh install. Thanks.
