How do I fill the tank container?
You can fill the tank container by right-clicking it with a bucket.
Is version 1.12.2 or lower still supported?
No. I moved on to newer Minecraft versions. These versions won't get any bug fix or feature updates.
Am I allowed to use your mods in a modpack?
Yes. But please make sure to give credit.
Where is the config file located? (Forge)
There are two types of configs. The config for the server side is located in your world folder in a subfolder called 'serverconfig'. The client side config is located in your '.minecraft' folder inside a subfolder called 'config'. Note that the client side and the server side config isn't the same. You can't put stuff from the server config into the client config. If you can't find the option you are looking for in the client config, try looking into the server config. There is always a server config, even if you are playing singleplayer, as it also uses an internal server.
Where is the config file located? (Fabric/Quilt)
The configs for a Fabric/Quilt mod are located in your '.minecraft' folder in a subfolder called 'config'. In there you can see a folder that is named like the mods ID. This folder contains the configs for the server and client.
I found a bug, how do I report it?
Please report any bugs on the GitHub page of the mod. Please describe your problem in detail and provide screenshots if possible. It is very important that you always provide log files, even if your game didn't crash, this helps a lot narrowing down the source of the problem.
Where can I see crafting recipes?
For recipes use JEI.
I translated your mod into another language. How do I send it to you?
Just upload the translation file to something like GitHub Gist and open a new issue with the issue template 'Translation'.
Do I need to install this mod on the client or the server?
All mods need to be installed on the client and the server unless stated otherwise. Always make sure, you are using the same version on both sides!
What does 'client' mean?
In the context of Minecraft, client means your game.
