The package apache2-doc contains the complete
Apache manual in various localizations for local installation and
reference. It is not installed by default—the quickest way to
install it is to use the command zypper in
apache2-doc. Once installed, the Apache manual is available at
https://localhost/manual/. You may also access it on
the Web at https://httpd.apache.org/docs-2.2/.
SUSE-specific configuration hints are available in the directory
/usr/share/doc/packages/apache2/README.*.
