Cloth Config API Mod for Minecraft 1.19.3, is a necessary and essential add-on to make use of certain Minecraft mods. That is, if this complement is not installed, some mods may not work correctly (or even run at all).
In the case of installing only Cloth Config API, it would be useless, since it will require at least another mod to be minimally functional. This is because, basically, it is a necessary link for the operation of certain Minecraft mods.
The installation is simple, since it will only be necessary to place Cloth Config API in the “mods” folder, inside the game location, the well-known “.minecraft”, something that will vary depending on the executable. Of course, it will be absolutely essential to have Forge previously installed.
The use of Cloth Config API is essential for the use of some Minecraft mods, i.e. if you do not have this add-on installed, some mods will not work.
