Images and Attachments
To add an image or attach a file to an article, first upload it using the "Edit" link in the "Attachments" section of the sidebar.
When uploading the file you will be prompted to give it a "slug" or name. You can use letters, numbers, and dashes (-) in the name. After it is uploaded, you can refer to it with:
{{name}}

{{mariadb-seal-pdf}}

You can also provide alt-text, like with links. For example, I can change the displayed text for the attachment above like so:
{{mariadb-seal-pdf|The MariaDB seal logo (in pdf format)}}
Which shows up like so:
The MariaDB seal logo (in pdf format)
