 # Tips & Tricks
+
 There are a few hidden features in the app which might not be obvious at first.
 
 ### Item description
+
 When searching for an item you can add the `,` delimiter to add descriptions directly.
 Did you also know that pressing enter when searching adds the first item to your shopping list?
