Hi,
I suggest adding a small section on the Installation page (https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Installation/)
just before the “Accessing your wiki” section:
Running XWiki
- If you’ve chosen to install within some servlet container, simply start your servlet container.
- If you’ve chosen the standalone distribution, execute the start_xwiki.bat batch file (on Windows) or start_xwiki.sh (on any linux or cygwin).You will need to either have the “java” executable in your $PATH or have the $JAVA_HOME variable set.
