robots.txt

Hello, a few weaks ago I finisched my work on page. Still didn’t understand how to revome robots.txt problem. It is what Google are showing for me:

“To fix the page description

If you want a proper description to appear in search results for your page, you must enable Google to read the page. If you don’t want the page to appear in search results at all, see the next section “Remove the page entirely from search results.”

The reason Google can’t read the page is that it has a special file (called robots.txt) blocking the page. Here’s how to remove the blockage:

If you are using a content management system for your website (for example, if your site is on Wix, Joomla, or Drupal), search for “robots.txt” in your host’s documentation to learn how to unblock your page or site to Google.”

Have I to remove robots.txt ? Or I need to do something more?
