Configuring Resynth
From the beginning, Resynth has made a point of being as configurable as possible. This mean that a large portion of Resynth can be changed, such as plant growth rates, seed drop chances, general difficulty, and whole lot more.

Due to the seriously large number of configuration settings, and with how much they have changed between versions, the configuration settings are not listed here. However, the configuration settings themselves are documented quite well, so you should have no trouble understanding and using them.

Configuring Resynth in 1.13.2 and 1.14.4
This section will attempt to give a rundown how to configure the 1.13.2 and 1.14.4 versions of Resynth.

First off, these versions of Resynth do NOT have a configuration GUI, so all settings have to be edited manually in the config files. It is recommended you completely close Minecraft before editing any of the files or your changes could be overwritten. I'd also recommend closing the config files before running Minecraft if you're having any issues.

Resynth has 3 configuration files, located within a separate folder called resynth within the main config folder in the .minecraft directory.

All configuration files are in the .toml format, which allow you to change numbers, values, as well as true and false settings. The files can be edited with any normal text editor.

The first file, called general.toml, holds most of the standard configuration settings, such as ore generation, ore drop amounts, tooltip toggles, and everything else that applies to the mod as a whole. To really see what can be changed, you'll have to look at the file yourself. What this file DOES NOT do, is hold configuration settings for any plants. That is handled in the other 2 configuration files.

The second file, called vanilla-plants.toml holds all the configuration settings for Vanilla and Resynth plants. Configuration settings are different depending on the plant type, but in general, growth rates, seed drop chances, and sometimes yield can be changed. The third file, called modded-plants.toml is exactly the same as vanilla-plants.toml however it holds configuration settings for plants added for other supported mods.

Configuring Resynth in 1.12.2
This section will attempt to give a rundown how to configure the 1.12.2 versions of Resynth.

The 1.12.2 versions of Resynth have an in-game configuration gui. It can be used to change all configuration settings in game. Most don't even need a world restart.

The 1.12.2 versions only have 1 configuration file, called resynth.cfg within the main config folder in the .minecraft directory. It holds all the configuration settings for the mod, including all settings for plants.

Changes in 1.13.2/1.14.4
Configuration was one of the biggest systems changed in the 1.13.2/1.14.4 rewrites.

This has resulted in a large number of changes, some good, some bad. This isn't a comprehensive list, but here's a rundown of the changes. The configuration gui has been removed in 1.13.2 and 1.14.4 versions - the configuration files have to be edited manually now. In 1.13.2 and 1.14.4 versions, resynth has 3 configuration files in a separate "resynth" folder within the config folder. In 1.12.2 versions, there is only one config file in the config folder. Most configuration settings were also renamed to be more descriptive and got better documentation. The format configuration files are written in has also changed.
