# Note Properties
At the top of the file you can have a section where you define your properties. This section is known as the [Front-Matter](https://learn.cloudcannon.com/jekyll/introduction-to-jekyll-front-matter/) of the document and uses [YAML formatting](https://www.codeproject.com/Articles/1214409/Learn-YAML-in-five-minutes).
> Be aware that this YAML section needs to be at the very top of the file to be valid.
For example, for this file, we have:
```markdown
---
type: feature
keywords: hello world, bonjour
---
```
This sets the `type` of this document to `feature` and sets **three** keywords for the document: `hello`, `world`, and `bonjour`. The YAML parser will treat both spaces and commas as the separators for these YAML properties. If you want to use multi-word values for these properties, you will need to combine the words with dashes or underscores (i.e. instead of `hello world`, use `hello_world` or `hello-world`).
> You can set as many custom properties for a document as you like, but there are a few [special properties](#special-properties) defined by Foam.
## Special Properties
Some properties have special meaning for Foam:
| Name | Description |
| ------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `title` | will assign the name to the note that you will see in the graph, regardless of the filename or the first heading (also see how to [[write-notes-in-foam]]) |
| `type` | can be used to style notes differently in the graph (also see [[graph-visualization]]). The default type for a document is `note` unless otherwise specified with this property. |
| `tags` | can be used to add tags to a note (see [[tags]]) |
| `alias` | can be used to add aliases to the note. an alias will show up in the link autocompletion |
For example:
```markdown
---
title: "Note Title"
type: "daily-note"
tags: daily, funny, planning
alias: alias1, alias2
---
```
## Foam Template Properties
There also exists properties that are even more specific to Foam templates, see [[note-templates#Metadata]] for more info.
