"you need to install forge" Install forge and mods in your client

The above is correct, despite the snarkiness.  More detail

Go here and download the latest build of forge (currently 272). 
http://jenkins.minecraftforge.net:7070/job/forge/lastBuild/

The download link isn't well marked, so here's a direct link
http://files.minecraftforge.net/minecraftforge-universal-4.1.4.272.zip

How to install it (for windows)
Go to Run (Windows key+r is the shortcut)

Type in %appdata%

Go to .minecraft (should be near the top)

Open it and go to bin

There should be a file there called minecraft.jar

Right click minecraft.jar and do 'open with...' winrar (if you don't have winrar, you need to install it - google)

Delete the file MATA-INF

Go to the file you downloaded, and copy everything in there over to the minecraft.jar folder

Close and you're done.

If you end up with any problems, it may be because you didn't download a fresh minecraft.jar.  I skipped that part because it wasn't a problem for me.
To do this, go back to minecraft.jar that you just edited, and delete the minecraft.jar file.  Then, open minecraft and connect, and it will download a new one.  Then just repeat the steps above.
