setup

The zero-to-multilingual path for MediaWiki: core language settings, URL structure per language, the Translate extension, and the content workflow that keeps translations current.

The advanced templating toolkit: named parameters, ParserFunctions patterns, #ifexist and #switch, and moving complex logic into Lua modules.

Which MediaWiki extensions are worth the maintenance: the editor stack, structured data, search, anti-abuse and translation, with honest notes on unmaintained ones.

The practical ParserFunctions reference: conditionals, #switch, #expr, string functions and URL helpers, with real syntax and usage notes.

Making SMW data visible where readers are: factbox settings, inline queries in article layout, accessible tables and navigation-oriented result formats.

The operations side of CirrusSearch: requirements, installation with Elastica, index creation, upgrade considerations and production maintenance.

The working Cargo pattern: declare tables, store from templates, query with #cargo_query — types, formats, `where` clauses and performance habits.

The modern MediaWiki hook system: extension.json registration, handler classes, arguments and return values, ordering, and debugging hook execution.
