You can create a definition (description) list with the following syntax:

: Item 1 : Something
: Item 2 : Something else

Item 1

Something

Item 2

Something else

If you need to put more than one line in the definition list, please use _ (underscore) at the end of the line you want to break (after one space). Remember not to insert any character after the underscore.

: Item 1 : Something _
another line
: Item 2 : Something else

Item 1

Something
another line

Item 2

Something else
