How to see the output of my rst text file

Hi,
I have created a txt file,with some content, which is formatted using rst (for ex:, headings using "=", table etc).  I would like to see, how this would look as an html page. Can I please know how to do this?
Sample txt file content:

==========
My heading
==========

Introduction
~~~~~~~~~~~~
My custome introduction

.. table:: **Default flavors**

============  =========  ===============  =============
  Flavor         VCPUs      Disk (in GB)     RAM (in MB)
============  =========  ===============  =============
  m1.tiny        1          1                512
  m1.small       1          20               2048
  m1.medium      2          40               4096
  m1.large       4          80               8192
  m1.xlarge      8          160              16384
============  =========  ===============  =============


I would like to know, how this would appear after formatting is applied.

Thanks,
Vinita
