# Welcome to Pacifist!

To get started, you can do one of the following:

1. If you would like to try to reinstall a file, but don't know what package it was installed from, you can use the “Search Receipts” feature.
2. If you would like to reinstall files that are part of your Mac OS X installation, click on the
   button. If your copy of Mac OS X comes on a physical medium such as a DVD or USB stick, be sure to insert that before clicking on the
   button (if your copy of Mac OS X comes on more than one disk, try Disk 1 first).
3. If you would like to inspect or extract files from another package or archive file, click on the “Open Package…” button to choose a .pkg, .zip, .tar, or .dmg file from which to extract files.

If you need help, please choose “Pacifist Help” from the Help menu.
