+Hi, welcome to Sabayon for the BeagleBone Black.
+
+First of all, you may want to install the image into a new SDHC card.
+Make sure to have enough space for it, for example, if you downloaded
+the 4GB version, make sure you're using a 4GB SDHC stick.
+
+Other requirements:
+-------------------
+
+  - a Linux distro to copy the image to the SDHC
+  - a SDHC reader
+  - a root shell on the Linux distro
+
+
+How to burn the image:
+----------------------
+
+Insert the SDHC memory into your reader (make sure that the LOCK
+switch is turned off). After a few seconds, type:
+
+  # dmesg | tail -n 10
+
+In the last kernel message lines you will be able to read the
+actual device name, might be something like "sdc" or in general
+"sdX" where X is just a letter.
+Make sure to see the same device name inside /dev directory.
+
+Once you got the name, just dump the image into that, in this
+example, we assume that the device is /dev/sdc and the image
+name is "Sabayon_Linux_8_armv7a_BeagleBoard_xM_4GB.img".
+Do this as root!
+
+  # xzcat Sabayon_Linux_8_armv7a_BeagleBoard_xM_4GB.img > /dev/sdd
+
+Once it is done, check for any error using:
+
+  # dmesg | tail -n 10
+
+And if it's all good, type:
+
+  # sync; sync; sync
+
+To make sure everything has been flushed to the device.
+
+At this point, extract your SDHC and place it into the BeagleBone Black.
+You're set!
+
+
+How to change keyboard mapping:
+-------------------------------
+
+Our images come with "keyboard-setup", a shell too that lets you easily
+do this, just type:
+
+  # keyboard-setup "<your keyboard layout code>" all
+
+Then reboot!
+
+
+How to change language:
+-----------------------
+
+Open /etc/locale.gen and add your locale (you can find a full list
+at: /usr/share/i18n/SUPPORTED).
+Make sure to add UTF-8 locales, this is what we support.
+Once you've added your line, just type:
+
+  # language-setup "<your locale, without the .UTF-8 part>" system
+
+Then reboot!
+
+
+You want to know more?

+and search for "BeagleBoard".
