SSRS report run from Browser Mode

Hi All,

I need to know couple of things about SSRS Report. 

I have a SQL Server 2012 version where reporting services are installed. When i run the report from MSCRM then reports run properly. I have a requirement to run the Report from Browser using an URL means when we paste the URL on browser then list of SSRS reports are displayed and we can click on any of the Reports and show the Results. Also this Browser is outside the Report Server means I want to run the Report where Report Server not installed. 

Can i do that using Sql Sever 2012. If possible then how.

If not possible then on which SQL Server version is supported to do the same.

Can anyone give me a step by step documentation.
