Thread:Project:Support desk/Wiki Bots

Hey I know this question have been asked many times. But I could not seem to find any page answering the question: 1. How to create a Wiki Bot. 2. How to program them.(e.g: language/guide)

All the page on mediawki and wikipedia only explain the purpose of creating a bot, and briefly explains how they work.

but none of them are helpful in answering my question.

what I want to do is simple: 1. create a wiki bot 2. bot look around for a word, and change it to another word.

any help will be appreciated.
