To edit a MediaWiki page, click on the "Edit this page" (or just "edit") link at one of its edges. This will bring you to a page with a text box containing the wikitext: the editable source code from which the server produces the webpage. For the special codes, see below.
After adding to or changing the wikitext it is useful to press "Preview", which produces the corresponding webpage in your browser but does not make it publicly available yet (not until you press "Save"). Errors in formatting, links, tables, etc., are often much easier to discover from the rendered page than from the raw wikitext.
If you are not satisfied you can make more changes and preview the page as many times as necessary. Then write a short edit summary in the small text field below the edit-box and when finished press "Save". Depending on your system, pressing the "Enter" key while the edit box is not active (i.e., there is no typing cursor in it) may have the same effect as pressing "Save".
You may find it more convenient to copy and paste the text first into your favorite text editor, edit and spell check it there, and then paste it back into your web browser to preview. This way, you can also keep a local backup copy of the pages you have edited. It also allows you to make changes offline, but before you submit your changes, please make sure nobody else has edited the page since you saved your local copy (by checking the page history), otherwise you may accidently revert someone else's edits. If someone has edited it since you copied the page, you'll have to merge their edits into your new version (you can find their specific edits by using the "diff" feature of the page history). These issues are handled automatically by the Mediawiki software if you edit the page online, retrieving and submitting the wikicode in the same text box.

[top]Minor edits

In the left column of the table below, you can see what effects are possible. In the right column, you can see how those effects were achieved. In other words, to make text look like it looks in the left column, type it in the format you see in the right column.
You may want to keep this page open in a separate browser window for reference. If you want to try out things without danger of doing any harm, you can do so in the Sandbox.

[top]HTML Tables

HTML tables can be quite useful as well. For details on how to use them and discussion about when they are appropriate, see Table.

[top]Templates

Some part of a page may correspond in the edit box to just a reference to another page, in the form {{name}}, referring to the page "Template:name" (or if the name starts with a namespace prefix, it refers to the page with that name; if it starts with a colon it refers to the page in the main namespace with that name without the colon). This is called a template. For changing that part of the page, edit that other page. Sometimes a separate edit link is provided for this purpose. Note that a change to a template effects every page that uses that template.
See Templates for a list of templates in use in BRWiki, and Template for helpful pointers on editing existing templates and making your own.

[top]Page protection

In a few cases the link labeled "Template:mediawiki:editthispage" is replaced by the text "Template:mediawiki:protectedpage" (or equivalents in the language of the project). In that case the page can not be edited.

[top]Position-independent wikitext

Wikitext for which the result does not depend on the position in the wikitext page:

• __NOTOC__, __FORCETOC__, see Section
  

[top]Separating edits

When moving or copying a piece of text within a page or from another page, and also making other edits, it is useful to separate these edits. This way the diff function can be usefully applied for checking these other edits.
