Navigating

The most natural way of navigating is by clicking wiki links that connect one page with another. The “front” button on the top navigation bar will always take you to the Front Page of the wiki. The “index” button will take you to a list of all pages on the wiki (organized into folders if directories are used). Alternatively, you can search using the search box. Note that the search is set to look for whole words, so if you are looking for “gremlins”, type that and not “gremlin”.

Markdown

This wiki’s pages are written in pandoc’s extended form of markdown. If you’re not familiar with markdown, you should start by looking at the markdown “basics” page and the markdown syntax description. Consult the pandoc User’s Guide for information about pandoc’s syntax for footnotes, tables, description lists, and other elements not present in standard markdown.

Markdown is pretty intuitive, since it is based on email conventions. Here are some examples to get you started:

*emphasized text* emphasized text
**strong emphasis** strong emphasis
`literal text` literal text
\*escaped special characters\* *escaped special characters*
[external link](http://google.com) external link

For headings, prefix a line with one or more # signs: one for a major heading, two for a subheading, three for a subsubheading. Be sure to leave space before and after the heading.

## Some examples...

Text...

Links to other wiki pages are formed this way: [Page Name](). (Gitit converts markdown links with empty targets into wikilinks.)

To link to a wiki page using something else as the link text: [something else](Page Name).

Note that page names may contain spaces and some special characters. They need not be CamelCase. CamelCase words are not automatically converted to wiki links.

Wiki pages may be organized into directories. So, if you have several pages on wine, you may wish to organize them like so:

Wine/Pinot Noir
Wine/Burgundy
Wine/Cabernet Sauvignon

Creating and modifying pages

Registering for an account

In order to modify pages, you’ll need to be logged in. To register for an account, just click the “register” button in the bar on top of the screen. You’ll be asked to choose a username and a password, which you can use to log in in the future by clicking the “login” button. While you are logged in, these buttons are replaced by a “logout so-and-so” button, which you should click to log out when you are finished.

Note that logins are persistent through session cookies, so if you don’t log out, you’ll still be logged in when you return to the wiki from the same browser in the future.

Editing a page

To edit a page, just double-click it, or click the “edit” button at the bottom right corner of the page.

You can click “Preview” at any time to see how your changes will look. Nothing is saved until you press “Save.”

Note that you must provide a description of your changes. This is to make it easier for others to see how a wiki page has been changed.

Creating a new page

To create a new page, just create a wiki link that links to it, and click the link. If the page does not exist, you will be editing it immediately.

Reverting to an earlier version

If you click the “history” button at the bottom of the page, you will get a record of previous versions of the page. You can see the differences between two versions by dragging one onto the other; additions will be highlighted in yellow, and deletions will be crossed out with a horizontal line. Clicking on the description of changes will take you to the page as it existed after those changes. To revert the page to the revision you’re currently looking at, just click the “revert” button at the bottom of the page, then “Save”.

Deleting a page

The “delete” button at the bottom of the page will delete a page. Note that deleted pages can be recovered, since a record of them will still be accessible via the “activity” button on the top of the page.

Uploading files

To upload a file–a picture, a PDF, or some other resource–click the “upload” button in the navigation bar. You will be prompted to select the file to upload. As with edits, you will be asked to provide a description of the resource (or of the change, if you are overwriting an existing file).

Often you may leave “Name on wiki” blank, since the existing name of the file will be used by default. If that isn’t desired, supply a name. Note that uploaded files must include a file extension (e.g. .pdf).

If you are providing a new version of a file that already exists on the wiki, check the box “Overwrite existing file.” Otherwise, leave it unchecked.

To link to an uploaded file, just use its name in a regular markdown link. For example, if you uploaded a picture fido.jpg, you can insert the picture into a page using the markdown: ![fido](fido.jpg). If you uploaded a PDF projection.pdf, you can insert a link to it using: [projection](projection.pdf).
