How do I implement the MPL? What's this “Exhibit A” thingy?

Question

I'm about to start an open-source project which shall be licensed under Mozilla Public License (MPL).

The problem is, I'm not sure what's this "Exhibit A" thing...

Am I supposed to put that wordy "Exhibit A" in each and every source file contained in the project?

And what about the MPL text proper; must I provide a complete text of the MPL in the root directory of the project?

I'd really appreciate it if someone can point me to a guide on how to release software under MPL (as opposed to using software with MPL).

TIA.
