How to use ClickOnce to deploy my C#(4.0)Visual studio 2010 windows form based Application?

We are developing C# 4.0 windows based application using visual studio 2010. Now we want to make an installable version of the exe using clickonce to deploy our application. I am new to .NET platform. So, please give me a step by step procedure to use clickonce to deploy my application.
While following steps :What should i need to given in Installation Folder URL Box(2 nd text Box):

A:

Here is the break down of the two paths in this wizard 

Publish Folder - Where should the Publish process put the ClickOnce deployment package
Installation Folder - Where will users of the application go to install the application from

Often times these are the same location.  For example when I deploy ClickOnce applications internally I publish to a network share.  This is the same place where users go to install the application.
One scenario where they would be different is when the users install from a web location.  In that scenario you'd often have a publish folder which was a network share or path on the local computer while the installation folder was a web site URL
