Notes:
* It is trivial to change from LXDE to [[Xfce]] (or any other desktop environment), adding a new user interface atop the minimal install is more advanced as manual setup of USB-Networking or wifi is needed to do so.
* All images have automount ( for USB-Sticks, external Hard-Drives etc. ) and ALSA sound support

==== '''Verify''' that your download is OK ====
* After you download the version you picked, verify its checksum to make sure the integrity of the downloaded file matches (in being an exact copy the one on the server)

#open up a terminal
# "'''sha256sum ~/downloads/pandian/<image.7Z>'''"   (input where you have the file and the one you chose to download)
# make sure it matches the given md5sum, if not, try to download another copy. This step isnt mandatory, but its there to make sure everything is fine before we proceed.

==== '''Unzip''' the downloaded image ====
*Unzipping 7z archives
# Open up a terminal (or do it your way)
# Enter"'''7zr e <image.7z>'''" 
# You now have an unzipped image

==== (Optional) '''Preparation''', find out where to install ====

This step helps you find out where the SD card is mounted.<br />

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 will get a list with the actual Block-Devices
* The SD-Card should be of type 'disk'

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

==== '''Install''' the image to the SD-Card ====
{{warning
| Warning, this will destroy everything on the device ! So please be very sure which device is you SD-Card !
}}
# Here it will be /dev/sd'''x''' 

(note that the x after the sd is the drive letter, it could be ''sd'''b''''' sd'''c''''' or ''sd'''d''''' and so on, lets say its sd'''c'''. Which means c is the drive letter for the SD-card and that sd- a and -b are in use for other things. <br />
<br />
When writing to the device, make sure not to include the following number, which is the partition ''sdc'''1''''' ''sdc'''2''''' etc. since we are using the base card here) <br />
<br />
This means considerations for partitions and filesystem are taken care of, so no need to worry about that. Do ''not'' pick the wrong drive however, since dd will happily write the image to somewhere it isn't supposed to if you just give it root privileges and hit enter.)<br />
<br />
#Copy image to SD-Card with "'''dd if=<image.img> of=/dev/sdx'''"

You now have Pandian installed on your SD card and its ready to go. :) However after copying the image to the SD-Card resizing the partitionspartitions is needed to fully utilize the space, since by default the install is limited to 2GB. (If your card is bigger Pandian is still limited to those 2GB)

====(Optional) '''Resize''' SD-Card ====

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

[[File:Gparted resize 001.png|800px|thumbnail|none|The actual partitions of the SD-CARD. Please select the correct device at the top right corner.]]
[[File:Gparted resize 002.png|800px|thumbnail|none|Rightclick to the second partition and select Resize/Move]]
[[File:Gparted resize 003.png|400px|thumbnail|none|You see the actual Size of this partition]]
[[File:Gparted resize 004.png|400px|thumbnail|none|Move the slider to the right, or set "Free space following" to 0]]
[[File:Gparted resize 005.png|800px|thumbnail|none|After you press the "Resize/Move" button, you get the preview of the new partition structure]]
[[File:Gparted resize 006.png|800px|thumbnail|none|When you press "Apply all operations", youve got a warning that you can loss your Data.<br />THIS IS THE LAST CHANGE TO CHECK IF YOU SELECTED THE CORRECT DEVICE. 

<br />Press Apply if everything is correct.]]

* After everything is fine, you have a fresh install of Pandian on you SD-Card
<br />

=== '''Startup''' wizard ===
* Upon first boot of Pandian, there is a first-start-wizard which guides you through some basic settings.
These are: Locale, timezone, time and date, password for admin and user setup and finally calibration of the touchscreen.
The script is located in /usr/sbin/pdSetup should you need to run it again.

==== Navigation ====
* Inside a dialog you can navigate with the cross/dpad
* Hit space to select a checkbox
* Moving between <Ok> and <Cancel> can be down with the use of TAB ( Tap Fn then tap Space )
* Acknowledge with Enter

*All done, enjoy :)

[[File:PandianDesktop.png|frameless]]

=== '''Network''' connection instructions:===

====normal ====
* Use network-manager

====minimal====
* Use ceni network manager

===(Optional) '''Update''' of Pandian system ===
* After you setup your Pandora, it is useful to update your system. It is a rolling release, which means since the image was made, the system is forever updated with new packages.
* open a terminal
* get root ( command is: "su" )
* enter "apt-get update" to download package information from the repositories
* enter "apt-get upgrade" to update all packages that are out of date
(pandian packages are also updated this way :)
* Note: to update only the pandian-packages enter "apt-get install pandian-full"

==== Up-To-Date Home directory ====
Normally files inside users home get overwritten ( if you say yes ) during upgrade. <br />
Since an change of this behavior, files inside the users home don't get changed anymore by pandian packages. <br />
Now settings of fluxbox and xinit/xinitrc are links. So The user can just unlink some of the settings and write there own, without getting overwritten from an upgrade. <br />
<br />
To get up-to-date with the fixes in pandian, you can initialize the home directory to default state. <br />
To do this, just run in an terminal ( as USER ):
* cp -a /etc/skel/. /home/<YourUserName>/

==== '''Upgrade Warnings''' ====
* if mpd is running, upgrade will fail. How to fix this:
** Open an terminal
** Login as root ( command "su" )
** Enter root password
** stop mpd with: /etc/init.d/mpd stop
** Kill it ( to be sure ): killall mpd
** upgrade again: apt-get dist-upgrade

==== Upgrade from "minimal" to "normal" ====
It is possible to upgrade from the "minimal"-image to the "normal"-image.
This can simlpy be done by installing the  pandian-lxde debian package
* get an connection to the internet(tm) with ceni
* open an terminal
* get root ( with command: "su" )
* update package list with: "apt-get update"
* install pandian-lxde with "apt-get install pandian-lxde"
* after everything is finished login with the user you setup before
* open an terminal
* get root ( with command: "su" )
* load keymap with "xmodmap /etc/skel/.pndXmodmap"
* the easiest way is to activate the first-start-wizard with "insserv firstuse"
* reboot and go through the wizard

===(Optional) '''Information''' ===

=== Additional Users/Groups ===
There are additional Users/Groups added to the standard debian-users
==== Groups ====
* admin
:This superuser privilege is used by sudo for admin task like shutdown etc.
* mpd
:This user/group has access to mpd-related files ( socket, pid-files )

==== Power-Modes ====
===== LID-Close =====
* If the lid is closed only the screen will be disabled
===== Low-Power-Mode / Shutdown =====
[[File:Lead Photo For Power modes0-2920264867079787.jpg|thumbnail|right|Switch]]
* Switch to left: Pandora will go to low power mode ( reduce CPU, Disable LID, Pause processes )
* Switch to right: Shutdown the pandora

==== pdcmd ====
* This script handles all system-related stuff, like lid, low-power, usb or wifi.
* This should run as root
<br />

|}

==== Several tweaks ====

==== '''Fluxbox''' ====
Fluxbox is the actual Desktop Environment for pandian. It is simple fast and easy to configure.

===== custom menu =====
You can setup your own menu-entry's for fluxbox:
* open an terminal ( or an editor ) as root
* create a new file in ./fluxbox/menu-mymenu
( Note: the menu -filename must be named menu-* )
* run: "gen-menu-fluxbox <username>" as normal user, to generate the menu-file
* your new menu is ready for use

===== autostart =====
You can setup your own autostart script in ~/.fluxbox/startup-*
for example you can use: ~/.fluxbox/startup-mystart
Nothing else must be done, just logout and login to test it ( or reboot )
===== Fixing broken keyboard layout =====
If your Pandian has a German keyboard layout, you might have some trouble because it does absolutely not fit US layout on the Pandora.
There is a work around this isse.

*Make sure, the file .pndXmodmap is read in on startup. Open the file ''.xsessionrc'' in your ''home'' directory and, if not existent, add following lines at the bottom of the file
  setxkbmap en_US
  xmodmap /home/yourUsername/.pndXmodmap
*There must be the absolute path (no "~/").

===== Making the Pandora Button work like the Windows key =====
Many users complained, their Pandora Button has no function in Pandian. This can be changed by mapping the button as ''"mod4"''. 

*Insert in the last line of the .pndXmodmap from your ''home'' directory:
  add mod4 = XF86MenuKB

===== Openbox =====
Pandian comes with an unconfigured Openbox as a possible session. Here are some config templates.

====== Use the Pandora key to start the menu ======
*If not existent,
  cp /etc/xdg/openbox/rc.xml /home/yourUserName/.config/openbox/
* Open the rc.xml with a text editor and search for the section <keyboard>.
* Insert the new keybind:
  <keybind key="XF86MenuKB">
      <action name="ShowMenu">
        <menu>root-menu</menu>
      </action>
  </keybind>

===== Intuitive Openbox configuration template =====
Prerequisites:
*mapped 'Pandora key' as 'Windows key'(see above)
*optional: use tint2 as panel

Features:
*Changing window by '''[Ctrl] + [up]/[down]'''
*Changing workspace by '''[Ctrl] + [left]/[right]'''
*Closing window by '''[Ctrl] + [Q]'''
*Screenshot (window): '''[Ctrl] + [Shift] + [Alt] + [F11]'''
*Screenshot (whole desktop): '''[Ctrl] + [Shift] + [Alt] + [F12]'''
*and some more

== Mounting internal NAND to /mnt ==

Pandora internal NAND exposes a raw flash interfaces. For such devices, the
Linux kernel exposes a special MTD abstraction and "mtd aware" filesystems may
give a better performance. Pandora uses UBIFS, which needs UBI volume
management to work.

# Install mtd-utils
# Run the following commands

<syntaxhighlight lang="bash">
# Attach mtd device 4 to UBI volume management 0
ubiattach -m 4 -d 0
# Mount first partition of the UBI group 0 to /mnt
mount -t ubifs /dev/ubi0_0 /mnt
# Attach mtd device 3 to UBI volume management 1
ubiattach -m 3 -d 1
# Mount first partition of the UBI group 1 to /mnt
mount -t ubifs /dev/ubi1_0 /mnt/boot
</syntaxhighlight>

===== Network Fix for pandian-minimal =====
If you download the '''pandian-mark2-minimal-hf_2014-01-02''' image there is a lack of tools for setup wifi networking. <br />
'''Note: For the actual download of pandian-minimal, wifi-network-tools are included'''
* Therefore download the fix and place it on the SD-Card where pandian is installed. (you need to have local superuser privileges on your own system as the SD contents aren't owned by your user)
* Boot pandian-minimal
* login with user: "root"
* switch to root-directory: "cd /"
* untar the network-fix: "tar -xf /path-where-file-is-located/pandian-mark2-minimal-networking_2014-01-03.tar.gz"
* setup the fix with command "pdMinimalNetwork"

* after the script is finished, run "ceni" and setup your wifi-connection

=== Installation ===

note: It is assumed here, that the card-reader load the card as /dev/sdc.
Please check before which device is your SD-card !
This can be checked with gparted. Minimum requirement 2GB SD-card.

# Download Image ( as 7z )
# Verify md5-checksum: <br /> pandian-stable-hf_2013-09-29.001.7z '''2a85bbb40bbe7c6e8f92f058e150951a'''   <br />   pandian-stable-hf_2013-09-29.001.img '''e62d101dc708de49af1ca7743e2df2bd'''
# Unzip with 7z ( in Linux with 7zr e <image.7z> )
# Copy image to SD-Card ( dd if=<image.img> of=/dev/sdx ) Don't specify "bs="

Username: ''Pandian'' <br />
Root password:   ''Root''   (change after intsallation as per instructions below)

#Open a terminal
#Type "su"
#Type "passwd"
#Enter your new root password when prompted, and then again to confirm.
#Dont forget your password

=== 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"
