There is a wide variety of software available for your OpenPandora, available as following:
Firstly, as Angstrom packages from the Angstrom repository (WRONG, FIX). These are installed to the same disk as your OS (normally the built-in NAND) and require careful negotiation of dependencies. These are not recommended for the uninitiated as they can permanently damage your installation (requiring a reflash) if not handled carefully. This is also unsuitable for large packages due to the small (512MB) space on the built-in NAND memory.
Secondly, if you have a different operating system or Linux distribution (such as [http://pandorawiki.org/Software_projects/OS/Slackware Slackware]) installed on an SD card, you can use archives or packages associated with that distribution.
Repositories, package-managers and installation procedures can probably found in the same place you found the alternative OS.
Thirdly and most importantly, the Pandora's own package format; .pnd files. Latest releases are available from [http://repo.openpandora.org the OpenPandora Repo], while older ones can be found at [http://dl.openhandshelds.org/cgi-bin/pandora.cgi the Open HandHelds archive].
To install a .pnd file, you can either:
'''Download it from one of the above websites and save it to one of the locations below:'''
The application(s) or game(s) will appear on the desktop or menu as soon as your pandora has had a chance to scan the SD card.
* <SD CARD>/pandora/apps - If you want it to appear on both the Xfce Desktop and in the menu system (this is the 'both' option in PNDManager)
* <SD CARD>/pandora/desktop/ - If you only want it to appear on Xfce Desktop
* <SD CARD>/pandora/menu/ - If you only want it to appear in Pandora Menu
'''Use a native package manager:'''
You can use [http://repo.openpandora.org/?page=detail&app=pndmanager-bzar PNDManager] or [http://repo.openpandora.org/?page=detail&app=pndstore PNDStore] to download software from the repo and save it in the appropriate directory in one operation. PNDManager is recommended as the most user-friendly way of doing this.
It is also worth noting the <SD CARD>/pandora/appdata directory (="folder"). By default, all .pnd programs save settings and data in <SD CARD>/pandora/appdata/applicationname/ and many will create this directory automatically when first run. If an application requires additional data, this is likely to be where you need to put it.
