==Methods of Updating==
===Basic Updating===
*If you have access to an internet connection on your XO, the fastest way to upgrade is by using the OLPC-update from the command line. This will only download the differences between your current version and the version you specify, and preserves all of your data. It assumes that you know the signed build number/name (available [here]), and if the install fails allows access to the "O" key reversion.
*If you do not have access to an internet connection, or if your current install is broken, you will need to use a USB key to reinstall. '''WARNING: This method will delete your data.''' This method requires that you download a signed build, have access to a USB key, and have access to a second computer on which you can make the download.
