RFTools Base Mod for Minecraft 1.19.3, 1.19.2, 1.19.1 and 1.19, is an essential complement for the correct execution of some Minecraft mods. That is to say, in the case of installing only RFTools Base, it would not have any use in the game, since it will be essential to install other mods.
To execute a game with RFTools Base, it will be necessary to follow the steps shown in the following paragraphs of this page, but it is important to remember that this add-on alone would not be useful in the case of executing a game.
The first step will be to download and install Forge, as it is an essential modification when running some Minecraft mods. Then, it will be necessary to download both RFTools Base, as well as the desired mods that require its use, which in this case, must be located in the “mods” folder, inside the game location “.minecraft”.
