Get started with Google Chrome Frame

Enabling Google Chrome Frame is simple. For most web pages, all you have to do is add a single tag to your pages and detect whether your users have installed Google Chrome Frame.

If Google Chrome Frame is not installed, you can direct your users to an installation page. If Google Chrome Frame is installed, it detects the tag you added and works automatically.

so yes they will need it only if they want it :)

The user will be offered Chrome, but they are not required to install or use it.

No, They need not to install Chrome Frame.

But, if visitors doesn't have google chrome installed it ask to install the chrome browser.
