+=== Ordered List Numeration Styles
+
+The browser automatically numbers ordered lists and selects a numeration style by list depth in the following order: decimal, lower-alpha, lower-roman, upper-alpha, upper-roman.
+
+AsciiDoc allows the author to override the numeration style for an ordered list.
+Here's an example of that output:
+
+[source,html]
+----
+<div class="olist loweralpha">
+<ol class="loweralpha" type="a">
+<li><p>a</p></li>
+<li><p>b</p></li>
+<li><p>c</p></li>
+</ol>
+</div>
+----
+
+In order to support this customization, you must assign the list-style-type property to the following classes on the <ol> element in your stylesheet.
+
+|===
+|<ol> class |list-style-type property value
+
+|arabic
+|decimal
+
+|decimal
+|decimal-leading-zero

+|loweralpha
