A Help and documentation #
SUSE® Linux Enterprise Desktop comes with various sources of information and documentation, many of which are already integrated in your installed system:
- Desktop help center
The help center of the GNOME desktop (Help) provides central access to the most important documentation resources on your system, in searchable form. These resources include online help for installed applications, man pages, info pages, and the SUSE manuals delivered with your product. Learn more in Section A.1, “Using GNOME Help”.
- Separate help packages for some applications
When installing new software with YaST, the software documentation is installed automatically, and usually appears in the help center of your desktop. However, some applications, such as GIMP, may have different online help packages that can be installed separately with YaST and do not integrate into the help centers.
- Documentation in
/usr/share/doc This traditional help directory holds various documentation files and the release notes for your system. Find more detailed information in Section 40.1, “Documentation directory”.
- Man pages and info pages for shell commands
When working with the shell, you do not need to know the options of the commands by heart. Traditionally, the shell provides integrated help by means of man pages and info pages. Read more in Section 40.2, “Man pages” and Section 40.3, “Info pages”.
A.1 Using GNOME Help #
On the GNOME desktop, to start Help directly from an application, either
click the button or press F1. Both
options take you directly to the application's documentation in the help
center. However, you can also start Help by opening a terminal end
entering yelp or from the main menu by clicking
› › .
To see an overview of available application manuals, click the menu icon and select .
The menu and the toolbar provide options for navigating the help center, for searching and for printing contents from Help. The help topics are grouped into categories presented as links. Click one of the links to open a list of topics for that category. To search for an item, click the search icon and enter the search string into the search field at the top of the window.
A.2 Additional help resources #
In addition to the
SUSE manuals installed under /usr/share/doc, you can
also access the product-specific manuals and documentation on the Web. For
an overview of all documentation available for SUSE Linux Enterprise Desktop check out your
product-specific documentation Web page at https://documentation.suse.com/.
If you are searching for additional product-related information, you can also refer to the following Web sites:
You can also try general-purpose search engines. For example, use the search
terms Linux CD-RW help or LibreOffice file conversion
problem if you were having trouble with the CD burning or with
LibreOffice file conversion.
A.3 More information #
Apart from the product-specific help resources, there is a broad range of information available for Linux topics.
A.3.1 The Linux documentation project #
The Linux Documentation Project (TLDP) is run by a team of volunteers who write Linux-related documentation (see https://www.tldp.org). The set of documents contains tutorials for beginners, but is mainly focused on experienced users and professional system administrators. TLDP publishes HOWTOs, FAQs, and guides (handbooks) under a free license. Parts of the documentation from TLDP is also available on SUSE Linux Enterprise Desktop.
A.3.1.1 Frequently asked questions #
FAQs (frequently asked questions) are a series of questions and answers. They originate from Usenet newsgroups where the purpose was to reduce continuous reposting of the same basic questions.
A.3.1.2 Guides #
Manuals and guides for various topics or programs can be found at https://www.tldp.org/guides.html. They range from Bash Guide for Beginners to Linux File System Hierarchy to Linux Administrator's Security Guide. Generally, guides are more detailed and exhaustive than HOWTOs or FAQs. They are usually written by experts for experts.
A.3.2 Wikipedia: the free online encyclopedia #
Wikipedia is “a multilingual encyclopedia designed to be read and edited by anyone” (see https://en.wikipedia.org). The content of Wikipedia is created by its users and is published under a dual free license (GFDL and CC-BY-SA). However, as Wikipedia can be edited by any visitor, it should be used only as a starting point or general guide. There is much incorrect or incomplete information in it.
A.3.3 Standards and specifications #

The World Wide Web Consortium (W3C) is one of the best-known standards organizations. It was founded in October 1994 by Tim Berners-Lee and concentrates on standardizing Web technologies. W3C promotes the dissemination of open, license-free, and manufacturer-independent specifications, such as HTML, XHTML, and XML. These Web standards are developed in a four-stage process in working groups and are presented to the public as W3C recommendations (REC).

The Internet Engineering Task Force (IETF) is an internationally active cooperative of researchers, network designers, suppliers, and users. It concentrates on the development of Internet architecture and the smooth operation of the Internet by means of protocols.
Every IETF standard is published as an RFC (Request for Comments) and is available free-of-charge. There are six types of RFC: proposed standards, draft standards, Internet standards, experimental protocols, information documents, and historic standards. Only the first three (proposed, draft, and full) are IETF standards in the narrower sense (see https://datatracker.ietf.org/doc/html/rfc1796).
