This document is an annotated index of popular articles and important information for improving and adding functionalities to the installed Arch system. Readers are assumed to have read and followed the Installation guide to obtain a basic Arch Linux installation. Having read and understood the concepts explained in #System administration and #Package management is required for following the other sections of this page and the other articles in the wiki.

Category:Multimedia includes additional resources.
Sound is provided by kernel sound drivers:
- ALSA is included with the kernel and is recommended because usually it works out of the box (it just needs to be unmuted).
- OSS is a viable alternative in case ALSA does not work.
For access to certain web content, browser plugins such as Adobe Acrobat Reader, Adobe Flash Player, and Java can be installed.
Codecs are utilized by multimedia applications to encode or decode audio or video streams. In order to play encoded streams, users must ensure an appropriate codec is installed.
The Network Time Protocol (NTP) is a protocol for synchronizing the clocks of computer systems over packet-switched, variable-latency data networks. See Time synchronization for implementations of such protocol.
For better security while browsing web, paying online, connecting to SSH services and similar tasks consider using DNSSEC-enabled client software which can validate signed DNS records, and DNSCrypt to encrypt DNS traffic.
Setting up a firewall
A firewall can provide an extra layer of protection on top of the Linux networking stack. While the stock Arch kernel is capable of using Netfilter's iptables and nftables, neither are enabled by default. It is highly recommended to set up some form of firewall. See Category:Firewalls for available guides.

This section contains popular input device configuration tips. For more, please see Category:Input devices.
Non-English or otherwise non-standard keyboards may not function as expected by default. The necessary steps to configure the keymap are different for virtual console and Xorg, they are described in Keyboard configuration in console and Keyboard configuration in Xorg respectively.
Owners of advanced or unusual mice may find that not all mouse buttons are recognized by default, or may wish to assign different actions for extra buttons. Instructions can be found in Mouse buttons.
Many laptops use Synaptics or ALPS "touchpad" pointing devices. For these, and several other touchpad models, you can use either the Synaptics input driver or libinput; see Touchpad Synaptics and libinput for installation and configuration details.
See the TrackPoint article to configure your TrackPoint device.
This section aims to summarize tweaks, tools and available options useful to improve system and application performance.
Benchmarking is the act of measuring performance and comparing the results to another system's results or a widely accepted standard through a unified procedure.
The Improving performance article gathers information and is a basic rundown about gaining performance in Arch Linux.
Solid state drives
The Solid State Drives article covers many aspects of solid state drives, including configuring them to maximize their lifetimes.
File index and search
Most distributions have a locate command available to be able to quickly search for files. To get this functionality in Arch Linux,is the recommended install. After the install you should run updatedb to index the filesystems.
Local mail delivery
This section contains frequently-sought "eye candy" tweaks for an aesthetically pleasing Arch experience. For more, please see Category:Eye candy.
You may wish to install a set of TrueType fonts, as only unscalable bitmap fonts are included in a basic Arch system. There are several general-purpose font families providing large Unicode coverage and even metric compatibility with fonts from other operating systems.
If spending a significant amount of time working from the virtual console (i.e. outside an X server), users may wish to change the console font to improve readability; see Fonts#Console fonts.
GTK+ and Qt themes
A big part of the applications with a graphical interface for Linux systems are based on the GTK+ or the Qt toolkits. See those articles and Uniform look for Qt and GTK applications for ideas to improve the appearance of your installed programs and adapt it to your liking.
This section applies to small modifications that improve console programs' practicality. For more, please see Category:Command shells.
It is recommended to properly set up extended tab completion right away, as instructed in the article of your chosen shell.
Aliasing a command, or a group thereof, is a way of saving time when using the console. This is specially helpful for repetitive tasks that do not need significant alteration to their parameters between executions. Common time-saving aliases can be found in Bash#Aliases, which are easily portable to zsh as well.
This section is covered in Color output in console.
Compressed files, or archives, are frequently encountered on a GNU/Linux system. Tar is one of the most commonly used archiving tools, and users should be familiar with its syntax (Arch Linux packages, for example, are simply xzipped tarballs). See Archiving and compression.
Emacs is known for featuring options beyond the duties of regular text editing, one of these being a full shell replacement. Consult Emacs#Colored output issues for a fix regarding garbled characters that may result from enabling colored output.
Using a mouse with the console for copy-paste operations can be preferred over GNU Screen's traditional copy mode. Refer to Console mouse support for comprehensive directions. Note that you can already do this in terminal emulators with the clipboard.
To be able to save and view text which has scrolled off the screen, refer to General troubleshooting#Scrollback.
Using terminal multiplexers like tmux or GNU Screen, programs may be run under sessions composed of tabs and panes that can be detached at will, so when the user either kills the terminal emulator, terminates X, or logs off, the programs associated with the session will continue to run in the background as long as the terminal multiplexer server is active. Interacting with the programs requires reattaching to the session.
