Pattern matching on the beginning of a string in f#

I am trying to match the beginning of strings in f#. Not sure if I have to treat them as a list of characters or what. Any suggestions would be appreciated.

Here is a psuedo code version of what I am trying to do

let text = "The brown fox.."

match text with
| "The"::_ -> true
| "If"::_ -> true
| _ -> false

So, I want to look at the beginning of the string and match. Note I am not matching on a list of strings just wrote the above as an idea of the essence of what I am trying to do.
