Android SDK/ADB help

I dont even understand how I am supposed to install it. I rooted my phone and flashed 2.1 onto it fairly easy enough. Now I want to give ADB a shot and I can't even figure out how to get it on my computer. I read the ADB thread and that didnt help. Any help would be greatly appreciated...

 

Here are 2 great easy to follow:

(these are general)
How To: adb for Windows the Easy Way
How To Use adb: All Commands and Options

Motorola droid specific:
Android Debug Bridge - Root Your Droid
Unix Commands - Root Your Droid
USB Debugging - Root Your Droid

Hope these help

 

Oooohhhhh those explain it a lot better. Thank you
