I've only started getting into Minecraft mods and forge. I have no idea what I'm doing. I just installed the update for forge so I have the latest forge. How do I get good mods, like the dungeons, veinminer and chance blocks... just stuff to make minecraft a little more exciting.
I good and easy foundation to start on would be downloading a already set to go mod pack. If that isn't the option I would get MultiMC which helps you install mods very easily.https://multimc.org/
In MultiMC once you opened the MultiMC.exe you can create a new instance and edit it to your liking. MultiMC even has buttons to auto install liteloader and forge for you. After you installed forge you should run the instance once so MC can create the necessary files.
After that you can navigate to MultiMC/instances/yourinstance/minecraft/mods where you can darg and drop most Forge mods.jar
Hope this help. If you need help pm me or visit this link for a example MultiMC mod pack:
