 First thing, back up your existing install using the "backup_for_reinstall"
 script. It will create an irlp_backup.tgz file on a USB stick - More on this
 later.

-  * Raspberry Pi Model B (any Revision SHOULD work, tested on a Rev 2)
+  * Raspberry Pi Model B, B+, or Pi2
+  * A **suitable** power supply. Please see [[powering_your_pi|Powering your Pi]]
   * DB-25 to IDC 26 parallel cable (or similar)
-  * USB sound card (most all should work, I am using the one listed below)
+  * Compatible USB sound card. Please see [[compatible_usb_sound_cards|IRLP Compatible USB Sound Cards]]
   * 2G (min) SD card (larger is better, but not required)
   * USB keyboard (for initial boot only)
+  * HDMI capable monitor, or an HDMI adapter to another style of monitor
