+Ordered and unordered lists can be easily created.
+
+For an ordered list, add the number you want the list
 to start with, like `1.`, followed by a space, at the start of each line for ordered lists.
 After the first number, it does not matter what number you use, ordered lists will be
 numbered automatically by vertical order, so repeating `1.` for all items in the
 same list is common. If you start with a number other than `1.`, it will use that as the first
 number, and count up from there.
-Add a `*`, `-` or `+`, followed by a space, at the start of each line for unordered lists, but
-you should not use a mix of them.
