Module:Hatnote

Þessi síða var afrituð frá ensku Wikipediu. Reynt hefur verið að aðlaga hana að íslensku Wikiheimildum með sem fæstum mögulegum breytingum. Það er gert til að forðast fjölverknað og spara tíma en einnig svo hægt sé að taka við uppfærslum og nýjum eiginleikum með sem minnstri fyrirhöfn. Leiðbeiningar um notkun hennar má finna á enska verkefninu. Einungis það sem lesandinn sér skal íslenskað. Ef frekari breytingar eru nauðsynlegar til að aðlaga hana að íslenska verkefninu skulu þær útskýrðar hér fyrir neðan.
