···14141515By default, Quartz will title the page `Folder: <name of folder>` and no description. You can override this by creating an `index.md` file in the folder with the `title` [[authoring content#Syntax|frontmatter]] field. Any content you write in this file will also be used in the description of the folder.
16161717+For example, for the folder `content/posts`, you can add another file `content/posts/index.md` to add a specific description for it.
1818+1719## Tag Listings
18201921Quartz will also create an index page for each unique tag in your vault and render a list of all notes with that tag.
20222123Quartz also supports tag hierarchies as well (e.g. `plugin/emitter`) and will also render a separate tag page for each layer of the tag hierarchy. It will also create a default global tag index page at `/tags` that displays a list of all the tags in your Quartz.
2424+2525+Like folder listings, you can also provide a description and title for a tag page by creating a file for each tag. For example, if you wanted to create a custom description for the #component tag, you would create a file at `content/tags/component.md` with a title and description.

3838+ - Folder descriptions should go under `content/<folder-name>/index.md` where `<folder-name>` is the name of the folder.
3939+ - Tag descriptions should go under `content/tags/<tag-name>.md` where `<tag-name>` is the name of the tag.
3740- Some HTML layout may not be the same between Quartz 3 and Quartz 4. If you depended on a particular HTML hierarchy or class names, you may need to update your custom CSS to reflect these changes.
3841- If you customized the layout of Quartz 3, you may need to translate these changes from Go templates back to JSX as Quartz 4 no longer uses Hugo. For components, check out the guide on [[creating components]] for more details on this.
