How to install my Minecraft mods?

I put the Modloader folder into the minecraft bin folder. Then put my mods into the mods folder found under appdata, I then tried to get on Minecraft and it crashed. Any help?

Okay. You stuffed up badly. To start, close minecraft (if it is running) and go into 'run' in the start menu. Type in %appdata% and press ENTER. It should take you to a folder with.minecraft in it. Go into the.minecraft folder and back up any save files (in the saves folder) and any texture packs (in the texturepack floder). Go back to the folder with.minecraft in it and delete it.

Launch minecraft and make sure that you type in your username and password correctly. Minecraft should run. Exit minecraft.

Now, drag all of the contents of mod loader into a file called "minecraft" in the bin folder. Make sure you do not drag it into a folder in the "minecraft" file. Also, delete the META-INF folder. You will have to open it with a program like Win Rar or 7 Zip.

Then, do the same with the mod (ps can you tell me what mod it is?) drag the contents of the mod into the file "minecraft".

MAKE SURE YOU DELETE THE META INF FOLDER

Run Minecraft. Tell me if it doesn't work.

Go to YouTube and find a video about it, that's the best place for this type of problem.
