 As you can see on the website, there is a lot of platforms, from ARMv5h to ARMv8h. It's also good to know the manufacturer of your ARM chip.** Broadcom is the manufacturer behind all Raspberry Pi chips**. You also maybe noted that if you have a Raspberry Pi 3 (ARMv8h), the installation instruction won't be different than from the Pi2. It uses the same archive in this case.
-Also note that you can do a search on the ArchLinuxArm website to find out [[https://archlinuxarm.org/packages|which package/software is available for your system]]. You'll see that Blender so far is only available for armv7h. This does not mean that other software won't run on it, but you'lll have to compile them yourself.

-It seems these install instructions only work from a Linux computer. You might try it though from a MacOSX platform if it supports ext4 filesystem (not sure it's there by default). If not, use any live Linux USB to fire up a temporary Linux system and follow the instructions.

 === How to find which /dev/sdX is my SD card? ===
-''fdisk -l'' will list all your disk. Just remove the SD card from your card reader. Do ''fdisk -l'', take a look at what you have. Then plug in the SD card again and redo ''fdisk -l'' again. The new lines that have appeared are the ones corresponding to your SD card.

 In my case, it looks like this:

-//You will notice that in my case, it's an SD card with 2 partitions already. It does not matter, they are going to be deleted by the installation procedure. In my case, the ''/dev/sd'' is ''/dev/mmcblk0''.//

+==== Installing Blender and other tools ====
+Once Arch Linux ARM files have been correctly written on the SD card, plug the card into a Raspberry Pi 2 and connect it to power and network cable (with a DHCP router on the other side and internet access ).
+Log in the system using:
+  * user: alarm
+  * pass: alarm
+=== Here is a series of command that you can perform ===
+''su'' will make us temporary root. (root password is ''root'', you might want to change that afterwards)
+As root, you can then perform ''pacman -Syu'' which is the Arch Linux way to update the system. It will download all the updates available and install them. //So you know, Arch Linux is a system that updates very frequently.//
+As you are probably more used to it, you might want to use ''sudo'' instead of ''su'' to do things. **sudo** is not installed by default. To install it, as root, do ''pacman -Syu sudo''. This will install sudo **and** verify that the system is up to date. Arch Linux only supports installing software on an updated system.
+To configure ''sudo'' for your user, as root, do ''EDITOR=nano visudo'' and uncomment the line that looks like this:
+<code>%wheel ALL=(ALL) ALL </code>
+Save the file. You can now exit ''root'' mode by typing ''exit''. The user ''alarm'' should now have access to ''sudo''.
+You guess now how to install Blender: ''sudo pacman -Syu blender''.
+This will install a lot of packages. Just wait and select the default suggestion when asked (just type ENTER).
+Once Blender is installed, verify that it's running by typing ''blender -v''. This is what is my output as I write this.
+<code>
+[alarm@alarmpi ~]$ blender -v

+And you're done.
+===== Conclusion =====
+The hardest part of all this is getting Arch Linux installed on an SD card and getting used to a slightly different Linux distribution for those more familiar with Debian/Ubuntu. But the documentation for Arch is one of the best I have seen. If you care to install and configure any other software, the official [[https://wiki.archlinux.org/|Arch Linux Wiki]] is the resource to go to.
+If you have any question. Don't hesitate to write me. --- //[[juego@requiem4tv.com|Ju]] 2016/10/07 01:57//
