Tags is a [[Core plugins|core plugin]] that allows you to add a type of metadata to your notes. It is enabled by default. You can use tags in Obsidian by typing a hashtag, followed by a word. Tags are applied to the entire note.

## Nested tags
Tags can also be nested like folders, so that you have parent tags and child tags. For example:
```
#people/family
```
Using this tag on the note [[Maria]] assigns her to both the tag `#people` and the tag `#people/family`.
Why wouldn't you just create two separate tags, `#people` and `#family`?
Nesting tags lets you use the same tag in different contexts. For this example, you could have:
- `#people/family`
- `#vacations/family`
- `#meetings/family`
- `#languages/family`
Nesting tags is also a way to organize your tags, in the same way you might do with folders.
