Demonstration Document
This whole section (wrapped in `---` is called frontmatter. It is YAML-formatted information and won't be rendered in the preview window. The section itself and any values inside are fully optional and can be omitted. It can contain any keys you wish, but Deepdwn only uses the following: `title` if available in the file list, but will show the filename instead if you haven't added a title yet. `category` is a single value, used for organizing similar content together. `tags`, like `category` are used to group content together. Unlike `category` a document can have multiple tags. `dir` may be either `ltr` or `rtl` to indicate that the current document should be edited and displayed either left-to-right, or right-to-left
