+Bare PC sample config
+=====================
+
+1. Build
+
+  First select the appropriate target you want.
+
+  For BIOS-based boot strategy:
+
+  $ make pc_x86_64_bios_defconfig
+
+  Or for EFI:
+
+  $ make pc_x86_64_efi_defconfig
+
+  Add any additional packages required and build:
+
+  $ make
+
+2. Write the pendrive
+
+  The build process will create a pendrive image called sdcard.img in
+  output/images.
+
+  Write the image to a pendrive:
+
+  $ dd if=output/images/disk.img of=/dev/sdc; sync
+
+  Once it's done insert it into the target PC and boot.
+
+  Remember that if said PC has another boot device you might need to
+  select this alternative for it to boot.
+
+  In the case of EFI boot you might need to disable Secure Boot from
+  the setup as well.
+
+3. Enjoy
