Inserting javascript into sharepoint editform.aspx

Question

I want to customize my sharepoint datepicker to prevent user from selecting past date. I have found the following code on this website

$(function () {
            $("<%=TextBox1.ClientID %>").datepicker(
            {
             minDate: +0,
            });
        });

but I am not sure where to insert this script. From what research I've done, it needs to be inserted in editform.aspx. I do not know where in the current script to place it, at the end of whats already there? I found I could not paste when I tried to paste it to the end. I am a complete novice at coding so any help would be greatly appreciated. I use SharePoint Designer 2010 and Workspace 2010.

Thanks
