Uploading a file to the wiki

Go to the page you want to have the file/image/whatever:

Edit it (tab on the top left). Go to where you want to add the link/image. Add in text that follows wiki syntax:

Save your edits. From the page you just edited, click on the new (red) link.

You are now on the uploading file screen:

Click on browse, find your file. Don't change the "Destination filename" unless you are prepared to go back and fix the link on the page above. Add in a summary of the file if you want. Click on "upload file."

After it successfully uploads, you get this screen:

Note the "file links" section, e.g., pages that link to this file. Click here to go back to the original page.

See that the file link is no longer red, e.g., the file exists.
