+# Note Properties
+
+At the top of the file you can have a section where you define your properties.
+
+> Be aware that this section needs to be at the very top of the file to be valid
+
+For example, for this file, we have:
+```
+---
+type: feature
+keywords: hello world
+---
+```
+
+Those are properties.
+Properties can be used to organize your notes.
+
+## Special Properties
+Some properties have special meaning for Foam:
+- the `title` property 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]])
+- the `type` property can be used to style notes differently in the graph (also see [[graph-visualization]])
+- the `tags` property can be used to add tags to a note (see [[tags-and-tag-explorer]])
