In addition to their books, the Linux Documentation Project has made a series of short documents describing how to set up particular aspects of GNU/Linux. For instance, the SCSI-HOWTO describes some of the complications of using SCSI – a standard way of talking to devices – with GNU/Linux. In general, the HOWTOs have more specific information about particular hardware configurations and will be more up to date than this manual.
There are Debian packages for the HOWTOs. doc-linux-text contains the various HOWTOs in text form; the doc-linux-html package contains the HOWTOs in (surprise!) browsable HTML format. Note also that Debian has packaged translations of the HOWTOs in various languages that you may prefer if English is not your native language. Debian has packages for the German, French, Spanish, Italian, Japanese, Korean, Polish, Swedish and Chinese versions of the HOWTOs. These are usually available in the package doc-linux-languagecode , where languagecode is fr for French, es for Spanish, etc. If you’ve installed one of these, you should have them in /usr/doc/HOWTO. However, you may be able to find more recent versions on the Net at the LDP homepage4.
