Please extend the INSTALL.txt

I read the INSTALL.txt and now, I think I'm a little bit stupid.

I can not understand the step 3 of the instructions.
The download link are wrong.

Extract the contents in the lib directory of the module

What exactly is this content?

The lib directory of the module not exist. For self creation: What is the name? lib or library or libraries?

Step 5
The direct link are wrong.

Please extend the INSTALL.txt and make the content understandable for dummies.
