Basically, in HTML, instructions are placed inside angle brackets "<" and ">". Some are "one time" instructions, but most have a start command and a stop command -- for example, angle brackets with an "I" inside starts italics and with a /I stops italics. That is the usual pattern, a "command" starts something and "/command" (both inside the angle brackets) stops it.
By the way, be sure to place your email address in the instruction below in place of " __Your_Email_Here__ " (note: don't overwrite the "quote marks" -- they need to stay).
