Do you know that plugin called CratesReloaded that costed money to just allow you to use some cool crate GUI with some fancy-smancy particle effects? Well, I’m bringing that to Sponge, and for free! Because I’m not greedy and partially because I can’t sell this on the forums. :3 andbecauseiwouldn’tanywayunlesssomeonecommisionedit
But yeah, this is a crate plugin. Go look at the media, since I’m one of the devs that do that on this site.

Donate on Patreon
Why should I donate, codeHusky?
Well, if your server is making money off of the keys from this plugin, and doing quite well from it, I can only ask you to donate to me on Patreon. It supports development of this plugin which in turn helps you keep making money and helping your server. You could pretty much think of it like this: I help you make money, and in turn you encourage me to keep helping.
You aren’t required to donate, though. But hey, pizza is always nice.
Donate here.

Redistribution
I am aware that GPLv3 allows you to redistribute this plugin wherever you want for the most part. While you can do this, I would like to personally request that you do not make a forum topic or mod page for this plugin on other sites without letting me know. I kinda want to manage how my plugin is portrayed, so I’ll most likely post it myself there if you ask. Thanks!~

Remote Connection Notice
HuskyCrates will contact the GitHub API to see if it is up to date. If it is not, it will warn the server owner in the logs. That is currently the only “phoning home” this plugin does.
