You are welcome to contribute to the KDE TechBase wiki. In order to keep a high quality of the articles there are some guidelines you should follow. This is a brief overview of the editing and contributing process.
The KDE TechBase wiki is meant to contain technical information all around KDE, for instance
The KDE TechBase wiki uses subpages. Take a quick look at the article about the Help:Wiki Structure. In short: Do not randomly add toplevel pages.
It is possible to translate KDE TechBase articles into other languages. Read the article about Help:Wiki Translation for further details.
You want to add new content. To keep high quality, please create the article in your userpage first (e.g. User:foo/My Acticle). Once it is ready, discuss the article with other developers and proof-read it. Finally, if a location is found, move the page.
After moving the page please add yourself to the watch list by clicking the Watch register. You will get a notice by mail whenever the page changes.
In the KDE TechBase wiki all readers are allowed to edit content and structure.
Make sure that you submit information which is relevant to the specific purpose of the wiki, or your content might be deleted. You can always use the Discussion or talk pages to ask questions or check to see if your idea will be accepted. Please make sure your contributions are not violating licenses.
To start editing a KDE TechBase page, click the Edit link at the tab on the top. This brings you to the edit page: a page with a text box containing the wikitext - the editable code from which the server produces the finished page. If you just want to experiment, please do so in the sandbox, not here.
You can just type your text. However, also using basic wiki markup to make links and do simple formatting adds to the value of your contribution. Please follow the style used in other wiki articles. If you follow this, your contributions will be more valuable as they won't need to be cleaned up later.
Write a short edit summary in the small field below the edit-box.
Example: "Fixed a typo"
When you have finished, click Show preview to see how your changes will look before you make them permanent. Repeat the edit/preview process until you are satisfied, then click Save page and your changes will be immediately applied to the article.
The wikipedia provides a quick introduction about the most important mediawiki syntax. Please read the Page editing help.
