Kit discord and steam

I've seen multiple servers with a /kit steam and /kit discord that requires you to join their group and discord.
Once you do so, you can redeem the kits.

I want to do something like this for my server but was unable to find any tutorials on how to do so.
If anyone can let me know how this is done, that would be great!

I'm also having another issue where my health as owner keeps resetting to 100 after taking damage. I would like to play on my own server without having to take owner off in the case I need to ban someone on the spot.

 

For the Steam group rewards use this: uMod - Steam Groups along with the Kits plugin. For Discord I couldnt find anything. Might be worth a google or even just a search on the forums. There probably is a Discord version as I have seen it in some server (but yet to see it working on a server lol). For your health bug probably another plugin doing that and not Oxide (chances are its not a bug but a feature). I am sure someone can offer better help but at 2 in the morning this is the best I can give.
