The help server is built with DokuWiki. At the moment, all admin help views are served from this server. At a later date, I plan to migrate all site help views to the help server as well.

1. Go to Download DokuWiki and configure your download to include:
   • Version: stable
   • Languages: en, de, fr, ko, th
   • Popular Plugins: CAPTCHA, Upgrade, Wrap, Translation.
2. Unzip the download to your web server directory, then run /path/to/wiki/install.php
3. Install bethico template for DokuWiki
4. Install the Icons Plugin for FontAwesome icons
5. Install the condition Plugin

• Add “admin” group for every administrator of the help server in User Manager.
• Create the language namespaces (e.g. en, fr, de, ko, th) and set permissions to Read only for @ALL in Access Control List Management
• Set “Use first heading for pagenames” to Always under Display in DokuWiki's Configuration Settings.
• Set “Top level for table of contents=2”, “Minimum amount of headlines that determines whether the TOC is built=1”, “Maximum level for table of contents=4”, and “Maximum section edit level=4” under Display in DokuWiki's Configuration Settings.
• Uncheck icon libraries other than FontAwesome from Icons plugin configuration in DokuWiki's Configuration Settings.

There are a few core hacks required to make this work as a help server, but they are simple and thus easy to maintain, even after an update of DokuWiki or any of the extensions.

• Copy 'doku.php' to 'help.php' in the DokuWiki root folder
• Create the language fallback to English for non-existent translation pages by adding 3 lines to /help.php at line #41, just below '$ID = getID();'. Remember to update after you add or remove languages.

  // bco: 20181114. Get requested language and set language fallback
  require_once(template('dispatcher.php'));
  $langcode = help_language();

• Modify 'help.php' and replace line #119+4 and #120+4

  //do the work (picks up what to do from global env)
  act_dispatch();

  with

  // bco: 20181114. Set language and load act_dispatch override
  init_lang($langcode);
  help_dispatch();

• Modify '/inc/template.php' and add after line #130 ($toc = $TOC) in function tpl_toc

  // bco: 20181116. Fix toc issues due to use of condition Plugin
  require_once(template('dispatcher.php'));
  help_toc($toc);

• Change 3rd parameter of 'dw_page.makeToggle' call in file '/lib/scripts/page.js' from null or 1 to -1 to initialize 'closed' instead of 'opened'.
• After a DokuWiki upgrade make sure that
  • If '/inc/actions.php' has been upgraded, reflect the changes in '/lib/tpl/bethico/dispatcher.php'
  • If '/inc/template.php' has been upgraded, reflect the changes in function tpl_toc
  • If '/doku.php' has been upgraded, reflect the changes in '/help.php'
• If you use a template other than 'bethico', you must copy '/lib/tpl/bethico/css/userstyle.css' to '/conf'
• Optional: replace favicon and logo in '/lib/tpl/bethico/images/'.

• Set the Help URL in the component configuration of com_bethico to

  'https://your.wiki.server/help.php?id={langcode}:{keyref}'

• Add a help button to view 'view' to open the help page

  JToolbarHelper::help('view', true);

• With English as the active language it will invoke

  https://your.wiki.server/help.php?id=en:view

Joomla's default help url:

{keyref} Help screen key reference
{language} Full language code (eg. 'en-GB')
