    Usage from wikitext

    This module cannot be used directly from wikitext. It can only be used through the Template:Tlx template. Please see the template page for documentation.

    Usage from Lua modules

    To use this module from other Lua modules, first load the module.

    local mLuaBanner = require('Module:Lua banner')
    

    You can then generate a side box using the _main function.

    mLuaBanner._main(args)
    

    The args variable should be a table containing the arguments to pass to the module. To see the different arguments that can be specified and how they affect the module output, please refer to the Template:Tlx template documentation.
