There are two different versions of the "MARK2" release:

Version	Description	Link	Checksums
normal	pandian with fully Desktop environment ( LXDE )	filedropper: pandian-mark2-hf2014-01-02 pandian.openpandora.org: pandian-mark2-hf_2014-01-02.7z	pandian-mark2-hf_2014-01-02.7z 3731d70a4d8ec59e79a046f34f69c5c809be73e38cfc91a5b580478b8f8c222f pandian-mark2-hf_2014-01-02.img 83b8d3fa5bd0588cfb8b11cfe6b827819e6311e98396a6e32c46c9692f072e96

If you are a "normal" user and like to have a desktop, just choose the normal "MARK2" release
If you don't like LXDE as Desktop you can change it, adding a user interface atop the minimal install is more advanced as setup of USB-Networking or interfaces for wifi is needed to do so.

pandian package ( in minimal and normal image )

This is the core package which contains following features:

ACPI support for brighter/darker-buttons, for lid and for low-power-mode
first-use-wizard
automount ( for USB-Stick, external Hard-Drives etc )
alsa sound support
pdcmd

pandian-lxde package ( only in normal-image )

This package features a fully desktop environment

Easy Wifi-Access trough network-manager
MediaPlayer ( mpd with gurlp )
nub-support
calibrator-application

After you download the files, verify the checksums !

Install the image

Linux

Verify you SD-Hardware

Check where your SD-Card is located. If you have an build in SD-Card-Reader this is normally /dev/mmcblk0p1 ( in Debian ) If you have an USB-Card-Reader this is something like /dev/sdc ( in Debian )

Open an Terminal and input "lsblk"
You get an list with the actual Block-Devices
The SD-Card should be as type disk

You can also try gparted to see which devices you have and identify the sd-card

Unzip

Unzip with 7z ( in Linux with 7zr e <image.7z> )

Copy the image to the SD-Card

Here it will be /dev/sdx
Copy image to SD-Card with "dd if=<image.img> of=/dev/sdx"

Resize SD-Card

After copy the SD-IMAGE to the SD-Card you need to resize the partitions to get the fully size of your SD-Card

This can be done with gparted on linux|gnu
start gparted

The actual partitions of the SD-CARD. Please select the correct device at the top right corner.

Rightclick to the second partition and select Resize/Move

You see the actual Size of this partition

Move the slider to the right, or set "Free space following" to 0

After you press the "Resize/Move" button, you get the preview of the new partition structure

When you press "Apply all operations", youve got a warning that you can loss your Data.
THIS IS THE LAST CHANGE TO CHECK IF YOU SELECTED THE CORRECT DEVICE.
Press Apply if everything is correct.

After everything is fine, you have your new fresh pandian on you SD-Card

First-start

When you first start pandian, there is an first-start-wizard which guides you through some basic settings for Pandian

Navigation

Inside an dialog you can navigate with the cross
With space you select a checkbox
<Ok> or to <Cancel> can be reached if you use TAB ( Tap Fn then tap Space )

Resize

Default installation is limited to 2GB, if you want to expand it, you can, provided you have installed it on a bigger SD-card and want to make use of the space.

Size will be changed with parted
parted /dev/sdx
show size with "print free"

(parted) print free # Model: USB Mass Storage Device (scsi)
Disk /dev/sdc: 7965MB# Sector size (logical/physical): 512B/512B# Partition Table: msdos

Number	Start	End	Size	Type	File system	Flags
	32,3kB	1049kB	1016kB		Free Space
1	1049kB	53,5MB	52,4MB	primary	fat32
2	53,5MB	1933MB	1879MB	primary	ext4
	1933MB	7965MB	6032MB		Free Space

we would like to resize the second partition to the nearly end ( -512MB for swap )

(parted) resizepart # Partition number? 2 # Warning: Partition /dev/sdc2 is being used. Are you sure you want to continue?# Yes/No? YES # End? [1933MB]? 7453MB this is how the partitions looks like after

(parted) print free * Model: USB Mass Storage Device (scsi)* Disk /dev/sdc: 7965MB* Sector size (logical/physical): 512B/512B* Partition Table: msdos

create Swap (optional)
