Refactoring jQuery code

First question so be kind ;)

I am trying to refactor this function:

jQuery(document).ready(function( $ ){

      //One
      $('.flip').click(function(){
        var link = $(this);
        $('.panel').slideToggle('slow', function() {
            if ($(this).is(":visible")) {
                 link.text('Close');                
            } else {
                 link.text('Read More');                
            }        
        });        
    });

    //Two
    $('.flip2').click(function(){
        var link = $(this);
        $('.panel2').slideToggle('slow', function() {
            if ($(this).is(":visible")) {
                 link.text('Close');                
            } else {
                 link.text('Read More');                
            }        
        });        
    });

    //Three
    $('.flip3').click(function(){
        var link = $(this);
        $('.panel3').slideToggle('slow', function() {
            if ($(this).is(":visible")) {
                 link.text('Close');                
            } else {
                 link.text('Read More');                
            }        
        });        
    });

    //Four
    $('.flip4').click(function(){
        var link = $(this);
        $('.panel4').slideToggle('slow', function() {
            if ($(this).is(":visible")) {
                 link.text('Close');                
            } else {
                 link.text('Read More');                
            }        
        });        
    });

    //Five
    $('.flip5').click(function(){
        var link = $(this);
        $('.panel5').slideToggle('slow', function() {
            if ($(this).is(":visible")) {
                 link.text('Close');                
            } else {
                 link.text('Read More');                
            }        
        });        
    });

    //six
    $('.flip6').click(function(){
        var link = $(this);
        $('.panel6').slideToggle('slow', function() {
            if ($(this).is(":visible")) {
                 link.text('Close');                
            } else {
                 link.text('Read More');                
            }        
        });        
    });

    //Seven
    $('.flip7').click(function(){
        var link = $(this);
        $('.panel7').slideToggle('slow', function() {
            if ($(this).is(":visible")) {
                 link.text('Close');                
            } else {
                 link.text('Read More');                
            }        
        });        
    });

    //Eight
    $('.flip8').click(function(){
        var link = $(this);
        $('.panel8').slideToggle('slow', function() {
            if ($(this).is(":visible")) {
                 link.text('Close');                
            } else {
                 link.text('Read More');                
            }        
        });        
    });

    //Nine
    $('.flip9').click(function(){
        var link = $(this);
        $('.panel9').slideToggle('slow', function() {
            if ($(this).is(":visible")) {
                 link.text('Close');                
            } else {
                 link.text('Read More');                
            }        
        });        
    });


    //Ten
    $('.flip10').click(function(){
        var link = $(this);
        $('.panel10').slideToggle('slow', function() {
            if ($(this).is(":visible")) {
                 link.text('Close');                
            } else {
                 link.text('Read More');                
            }        
        });        
    });





    });

I want it to be just one fuction that can do this. Where should I turn? What article should I read? I am really stuck on this!

Cheers,

<h3 class="text-center">How to use promotional feather banners?</h3>
Feather banners are a brilliant way to guide people around your business premises, or liven up a local event with some custom advertising. These flags are very quick to set up — use them to transform a space in minutes.
<div class="panel6">

These branded flags can be used in a cluster or on their own — depends on the effect you want to create. A single large flag can make a good impression on people passing by on foot or in their cars, whereas a cluster of smaller or medium flags can make a nice walkway through a retail forecourt, or show people where to walk at a large event. All our flags come in a range of sizes and sets to suit different budgets — just speak to one of the team who can take you through all the different options.

Businesses that need to grab people’s attention fast often opt for flag advertising — real estate agents, food retailers, and car dealerships being just some of our regular flag customers. <strong>Our flags help Aussie businesses really stand out against their competition.</strong>

Our flag bases and poles are all sold separately — we will help you find the right flag bundle for your needs. We stock both hard ground and soft ground feather flag kits so that you are always prepared for any event or eventuality. See for yourself how easy they are to set up and install.
