 # Metadata explanation
 Metadata is everything at the beginning of the markdown file between `---`.
-It's written in a format similar to yaml.
+It's also written in toml. Why toml? I already use it's parser so it's easy to implement.
+Besides it's readable and easy to write.
 
 ## Fields
 - author – the author of particular blog entry | string
-- date – date of writing an entry | string YYYY-MM-DD
+- date – date of writing an entry | date
 - title – title of blog entry | string
-- tags – tags for blog entry. | json like list
+- tags – tags for blog entry. | array
 
 ## Example
 ```
