+### Lists
+
+* A list ends with two endlines, i.e., `\r\n\r\n`
+* List items are separated by one endline
+* List type is determined by the first item.
+  * `NUMBER ; DOT` will be ordered list
+  * ` - ` or ` * ` will be unordered list
+* If the first item does not start with `NUMDER;DOT;Space| "- " | "* "`, the list type will be default to unordered list
+* Ordered list start number is determined by the first item
+  * The subsequent counting is `+1` for each list item
+* Two spaces as one level of indentation.
+* A tab, `\t` character will be interpreted as four spaces, therefore two levels of indentation.
