4: ## Purpose of this guide
5:
6: This guide describes the installation and the configuration of the NetBSD
7: operating system as well as the setup and administration of some of its
8: subsystems. It primarily addresses people coming from other Unix-like operating
9: systems, and aims to be a useful guide in the face of the many small problems
10: one encounters when using a new tool.
11:
12: This guide is not a Unix tutorial: basic knowledge of some concepts and tools
13: is assumed. You should know, for example, what a file and a directory are, and
14: how to use an editor. There are plenty of books explaining basic Unix and
15: operating system concepts, and you should consult one if you need more
16: background information. It is better to choose a general book and avoid titles
17: like "Learning Unix-XYZ, version 1.2.3.4 in 10 days", but this is a matter of
18: personal taste.
19:
20: Originally, the guide has been a book, which was subsequently moved to the wiki
21: to make it easier to contribute.
22:
23: If you have additions or comments to the guide, but don't want to create an
24: account, feel free to post your submissions to the
25: [www team](mailto:www@netbsd.org) or the
26: [docs mailing list](netbsd-docs@netbsd.org). The text is maintained in
27: Markdown, and you can use the button in the top right corner to show the source
28: of an article.

259: ## Guide history
260:
261: This guide was born as a collection of sparse notes that Federico Lupi, the
262: original author of the NetBSD Guide, wrote mostly for himself. When he realized
263: that they could be useful to other NetBSD users he started collecting them and
264: created the first version of the guide using the groff formatter. In order to
265: "easily" get a wider variety of output formats (e.g. HTML and
266: PostScript/PDF), he made the "mistake" of moving to SGML/DocBook, which
267: was the format of the sources. Maintainership was picked up by the NetBSD
268: project and its developers later, and the format was changed to XML/DocBook
269: later due to better tools and slightly more knowhow on customisations.
270:
271: In 2012/2013, the guide was converted in a Google Code-In task by Mingzhe Wang
272: (wmzhere) to Markdown. In early 2013, it was integrated to the NetBSD wiki,
273: along with removing old chapters, restricting numbering schemes and some
274: reformulations.
275:
276: You can still get the
277: [old version of the Guide](http://netbsd.org/docs/guide), which is not
278: maintained anymore.
