Whether you can edit an article or add new articles depends on the rights of the usergroup you belong to. If you want to add a new article, see Help:Starting a new page. Making changes to an existing article only takes a few clicks.
For existing pages:
- Click the edit page tab
- Make changes to the text in the edit box. If you're making normal changes to the text like fixing spelling mistakes or grammar, inserting new sentences, etc, then you don't have to worry too much about formatting. When you do need to use some type of formatting, you do it using wiki syntax, see Help:Formatting for some of the common types of formatting used.
- Enter a short note in the Summary box describing your changes.
- Preview your changes with the Preview button.
- Click the Save page button.
Every article has its own discussion page where logged-in users can ask questions, make suggestions, or discuss corrections. Click the discussion page tab to reach it. You can sign your message by writing 4 tildes (~~~~). The wiki software turns them into the current time and your username.
