Basic HTTP Service Help please?

So basically I want to create a Message that has some information from a website and I tried to do that as you can see....

hs = game:GetService("HttpService")
test = hs:GetAsync("http://example.com", true) 
local msg = Instance.new("Message", workspace)                
msg.Text = test

However the text is in HTML Language... Now what I want to do is get content of a website and put it inside of the message so that anyone can understand it in other words so it doesn't look complicated rather it looks like how the website would originally look... If you kind of get what I mean please don't lead me to the Roblox Wiki I've already read that it didn't help me with figuring this out. I would also appreciate it if you told me how I would use the function :PostAsync().

Any examples or explainations I am greatful for.

You must Make/buy a website and then Make a file - index.html and Enter to content this code

<html>
<body>
Message what u want
</body>
</html>

After that you must change that http://example.org to for example http://yourdomain.com/index.html and it will work
