Tags in Obsidian

This is a tag

For a tag, the # is right next to the word. For a heading, there is a space between the # and the word.

You can add tags to an entire page by adding Frontmatter at the top of the page, like so:

---
tags:
- MyTag
- another-tag
- tree/of-tags
---

Note:

All items with a given tag are presented as being related but its hard to see how. Theyre just a jumbled, unordered list.
