fatal: does not appear to be a git Repository

Question

I’m trying to set up a private Git repository on shared hosting via SSH.

I do the whole process of configuring the keys etc,e giving git init in the repository but when I put

git remote add deploy ssh://USUARIO@IP-DO-SERVIDOR:2222/public_html/wordpress-studies

At the time of giving git push -u deploy master appears:

fatal: '/public_html/wordpress-Studies' does not appear to be a git Repository fatal: Could not read from remote Repository.

What does that mean?

EDIT:

Ok... what I was missing was that I didn’t know the difference between the repository and the folder that had the work tree from which I would receive the files from the Bare repository. But I still can’t solve the problem.

What have I done so far? I created a repository in the off-site public_html folder called "wordpress-Studies.git". I applied the "git init --Bare" command to it; having done so, I created and edited the post-receive file with:

#!/bin/sh
  echo "********************"
  echo "Post receive hook: Updating website"
  echo "********************"

  GIT_WORK_TREE=/public_html/wordpress-studies

I saved and made it executable with "chmod +x hook/post-receive." and git remote add deploy ssh://MEUSERVIDOR/home/protodes/wordpress-Studies.git

And then...

git remote add origin [email protected]:rafandrade/wordpressstudies.git

when I give "git push deploy master" it appears here:

$ git push origin master

But when I check the folder it doesn’t contain the files that were added in the commit
