+To customize your pages even further, you can add a Front Matter to your files.
+
+Front Matter is a block you add at the top of your file and looks like this:
+
+    ---
+    title: Hallo Welt
+    date: 12th December 1984
+    ---
+
+## Changing the title
+
+The only implemented customization right now is the override of the title.
+
+If your file is named "Hello_World_de.md" and your front matter is the one displayed above, you will get a page named "Hallo Welt"
+
+## For Developers
+
+You can then access this information in each `Content` with `$content->getAttributes()`
