 As a basic installation is minimal, the system can then be expanded and fully customized with kernel modules, drivers, Xorg graphics, various Window Managers or Desktop Environments, sound and any other desired software. As dCore imports software directly from pre-compiled Debian/Ubuntu repositories, thousands of packages are available. Additional software is also available from the dCore pre-built repository, such as kernel modules and select lightweight software no longer available from Debian/Ubuntu. As a basic installation is minimal, the system can then be expanded and fully customized with kernel modules, drivers, Xorg graphics, various Window Managers or Desktop Environments, sound and any other desired software.

 +This guide uses a typical persistent installation that requires using the ''backup'' command to save session changes in /home/, /opt/ and other directories. Additional boot codes (linked above), such as home=sda1 and opt=sda1, can also be used for systems set up with these dedicated partitions.
 +
 +Although classic, vi is often considered less than user friendly. It is, however, an efficient command line editor that is quite simple to use once a few keyboard commands have been memorized, there are several tutorials online. Regardless, users that wish to use a more user friendly CLI-based editor could import and load ''nano'', provided the dCore install has a working network connection:
 +<code>
 +sce-import -b nano # Import nano, add to sceboot.lst so it's always available
 +sce-load nano      # Load nano for use during this session (not required on reboot)
 +nano file_name     # Open file with nano, prepend sudo for root owned files
 +                   # The ^ command key (eg. ^X to exit) denotes the Ctrl key 
 +</code>
 +
 +Congratulations, already imported and loaded your first extension!

-Like Tiny Core Linux, an installation is not persistent unless a TCE directory has been set up. This stores all imported SCE extensions so they are persistent and available across reboots. The TCE directory also stores the mydata.tgz backup file when running the ''backup'' command. By default this contains any files located in the home and opt directory. If it is necessary to add additional files for backup outside of these default directories, they should be entered into /opt/.filetool.lst. Any files or directories the user wants to exclude from ''backup'', to keep the backup file smaller, should be added into /opt/.xfiletool.lst. Although these files can be manually modified, when working in a graphic environment it may be easiest to use the Backup Restore GUI, launched by running ''filetool'' or accessed via System Tools -> Control Panel -> Backup/Restore.+Like Tiny Core Linux, an installation is not persistent unless a TCE directory has been set up.

-Additional important configuration files include:+Most system related configuration files are located in the /etc/sysconfig/ and /opt/ directories. Additional important configuration files for launching executables and applications at boot:
   * /opt/bootlocal.sh: Enter desired root commands to run in the background during system boot.   * /opt/bootlocal.sh: Enter desired root commands to run in the background during system boot.
   * /opt/bootsyn.sh: Enter desired high priority root commands to run during system boot.   * /opt/bootsyn.sh: Enter desired high priority root commands to run during system boot.

 As all other critical files are stored within the TCE directory, a periodic copy/paste of this entire directory to other media effectively backs up the entire system, including SCE, mydata.tgz and mydatabk.tgz files. As all other critical files are stored within the TCE directory, a periodic copy/paste of this entire directory to other media effectively backs up the entire system, including SCE, mydata.tgz and mydatabk.tgz files.
  
-When the system is set up and is running well, a safe backup should periodically be performed via ''filetool.sh -sb'', to backup mydata.tgz to mydatabk.tgz. Numerous mydata.tgz or mydatabk.tgz backup files can be manually kept if desired. The mydata.tgz file can be manually replaced with a known good version in the event of file corruption or system misconfiguration.+When the system is set up and is running well, a safe backup should periodically be performed via ''filetool.sh -sb'', to copy mydata.tgz to mydatabk.tgz. Several mydata.tgz or mydatabk.tgz backup files can be manually saved if desired.

 Although rare, there is a possiblity an updated SCE may not work correctly due to an RC bug, broken Debian/Ubuntu package or corrupt file system. Modifying SAFEBACKUP=TRUE in /etc/sysconfig/sceconfig will automatically backup the old SCE in /etc/sysconfig/tcedir/sce/backup/ when running ''sce-update'' or re-importing an SCE, which can be manually restored as needed. Note the modified /etc/sysconfig/sceconfig file needs to be added to /opt/.filetool.lst and ''backup'' run for the configuration change to be saved. Although rare, there is a possiblity an updated SCE may not work correctly due to an RC bug, broken Debian/Ubuntu package or corrupt file system.

-Aside from the updates and backups discussed above, dCore requires little maintenance. An advantage of using self-contained extensions that link to the main file system is that when the SCE is removed, all traces of the main program and dependencies are gone, with the exception of home direcctory configuration files.+Aside from the updates and backups discussed above, dCore requires little maintenance.
