Installing Mods prerequisites
- Knowledge of Zipping/Unzipping files, and working with a good archive utility (such as WinRAR, 7zip, etc.).
- Knowing how to submit proper bug reports.
- Knowing how to actually install the mod and its prerequisites.
- Knowing how to accurately read and follow instructions.
- Knowing which mods conflict with each other and which do not.
You might be able to get away without knowing how to do a few of these things, but if your copy of Minecraft breaks, then you should seek help from somebody in the modding community (preferably the mod author). If you view this as a great opportunity to learn something new, then you're on the right path!
