Redirecting index.html file

I would like to redirect my index.html file to the latest post that I have in my _posts folder as oppossed to an archive type view of all posts by default.

the only way I have been able to make this work thus far is have ablank index. html wit the following code.

<html>

   <head>

      <title>HTML Meta Tag</title>

      <meta http-equiv = “refresh” content = “2; url = https://jonbcarroll.com/2019-10-01-shotgunweddings/” />

   </head>

   <body>

      <p>Hello HTML5!</p>

   </body>

</html>

This solution though would require I update that redirect link everytime I makea new post.

if anyone can give advice on how to do this it would be greatly appreciated.  

Site is www.jonbcarroll.com  or http://jonbcarroll.github.io

for example i would like to to bring up the latest post which today would be

https://jonbcarroll.com/2019-10-01-shotgunweddings/

thanks in advance ! 

Redirect to {{ site.posts[0].url }}
