How to use the export feature (.txt) with Media Wiki syntax?
You need to use the pre-installed MediaWiki Publisher extension (requires Java):
- select the ▸ menu;
- in the save dialog, chose MediaWiki (.txt) file format;
- a .txt file is exported and written in wikitext; you can open this file with a simple text editor;
- cut and paste it in the wiki.
Note: paragraph indentations are not recognized and should be ideally handled by theof the wiki itself.
= Header 1 = == Header 2 == === Header 3 === '''Bold''' ''Italic'' paragraph. # Numb- # -red lists. * Bu- * -llets.
