You can control which packages will be installed by selecting an environment in the `Software Selection` dialog in the graphical installation (see xref:install/Installing_Using_Anaconda.adoc#sect-installation-gui-software-selection[Software Selection]). This dialog does not provide a way to choose individual packages, only predefined sets. However, you can use the [application]*DNF* package manager to install additional packages after the installation. See the [citetitle]_xref:fedora:system-administrators-guide:index.adoc[{PRODUCT} System Administrator's Guide]_.
Usually, drivers for system devices are already supported in the kernel provided by {PRODUCT}. However, occasionally, support for devices that have been released recently could be missing. In these cases, a driver update enabling your device may be available.
Two separate configuration tools are part of {PRODUCT}. If you installed the [application]*GNOME* desktop environment (the default {PRODUCT} environment, installed for example as part of the {PRODUCT} Workstation Edition), the [application]*GNOME Initial Setup* utility will open; for all other graphical environments, the [application]*Initial Setup* tool serves the same purpose.
This utility allows you to configure several user-specific settings, such as system language or the default keyboard layout. Use the `Next` and `Previous` buttons at the top of the window to navigate between screens. Some screens (`Configure online accounts` in particular) are optional and can be skipped using the `Skip` button in the top right corner. このユーティリティーでいくつかの設定ができます。たとえばシステム言語やキーボード・レイアウトです。ウィンドウ上部にある `Next` と `Previous` ボタンを使えば、画面を移動できます。いくつかの画面 (`Configure online accounts` in particular) はオプショナルであり、右上コーナーにある `Skip` ボタンでスキップできます。
This chapter describes the initial setup tools which open after you finish the installation, reboot the system, and log in for the first time.
The `root` password, which is configured during the installation, is required for accessing the system as the `root` user. Without this password you will not be able to configure your system or install additional software. If you lost or forgot your `root` password, you can reset it by following the steps described in xref:install/Troubleshooting.adoc#sect-trouble-after-reset-root-password[Resetting the Root Password].
The [application]*GNOME Initial Setup* utility will be displayed after you log in for the first time with any user account, as long as your first login is in the [application]*GNOME* desktop environment. [application]*GNOME* デスクトップ環境でのユーザーアカウントの初回ログインであれば、ログイン後に [application]*GNOME Initial Setup* ユーティリティーが表示されます。
The [application]*DNF* package manager is used for updating installed packages. For more information about updating your system with [application]*DNF*, see the [citetitle]_xref:fedora:system-administrators-guide:index.adoc[{PRODUCT} System Administrator's Guide]_.

Perform an initial system update
New software is installed from _package repositories_. Package repositories are organized sets of software and metadata that can be accessed by the [application]*DNF* package manager. By default, several update repositories provided by {PRODUCT} are configured automatically and you can install updates and additional software from those. However, if you want to set up additional repositories, for example ones containing your own software, some extra steps are needed.
Install driver updates
Install additional packages
In most cases, network access is configured during the installation process, either in the [application]*Anaconda* installation program (see xref:install/Installing_Using_Anaconda.adoc#sect-installation-gui-network-configuration[Network & Hostname]) or in a Kickstart file (see xref:appendixes/Kickstart_Syntax_Reference.adoc#sect-kickstart-commands-network[network (optional) - Configure Network Interfaces]). For information on configuring the network after the installation, see the [citetitle]_{PRODUCT} Networking Guide_, available at link:++https://docs.fedoraproject.org/++[].
If you installed {PRODUCT} from a full installation ISO image (such as the Workstation live image or full Server DVD), it is recommended to perform an initial system update, because your installation media likely contained older versions of software packages. During the initial update, all installed packages are updated to their latest available versions. Updates to packages provide security fixes, bug fixes and enhancements.

For information about configuring additional software repositories, see the [citetitle]_{PRODUCT} System Administrator's Guide_, available at link:++https://docs.fedoraproject.org/++[].
Devices necessary to complete the installation can have driver updates provided before the installation begins. If a device is missing a driver, but it is not essential during the installation, it is recommended to wait until after the installation completes, and install additional drivers afterwards. For instructions on installing and enabling additional drivers on the installed system using [application]*RPM* and [application]*DNF*, see the [citetitle]_xref:fedora:system-administrators-guide:index.adoc[{PRODUCT} System Administrator's Guide]_.
