git clone does not appear to be a git repository

Client Side:
If you get the error message:
fatal: ''/D:/project/myrepo'' does not appear to be a git repository

when trying to clone a git repository via SSH using OpenSSH on a Windows Server, for example:
`$ git clone ssh://[email protected]:22110/D:/project/myrepo`


#####################################################################

Server side:
Make sure D:/project/myrepo has been initialized with `git init`, and change the default shell of OpenSSH from powershell to bash.exe, which comes with git-bash.

Open regedit
Go to `HKEY_LOCAL_MACHINE\SOFTWARE\OpenSSH` and add a new String Value C:\Program Files\Git\usr\bin\bash.exe without double quotes ' " '

github -> local repo <-(pull, push) computers

Server (Local repo, has SSH [email protected], and to handle git pull request from sub computers):
  - create a folder 
  - `$ git init --bare`

Main Computer (not the server, to handle git pull from master github):
  - `$ git clone https://github.com/xxx/yyyy`    (the repo from github)
  - `$ git remote -v`                            (check origin urls )
    should get something like this
    ```
      origin  https://github.com/xxx/yyyy (fetch)
      origin  https://github.com/xxx/yyyy (push)
    ```
    fetch is the one to git pull from master github
    push is the one to push changed/update 
  - need to change that push into server local repo
    `$ git remote set-url --add --push origin "ssh://[email protected]/C:/the_location_git_that_was_just_git_init_bare"`  (to add)
    `$ git remote set-url --delete --push origin "ssh://[email protected]/C:/the_location_git_that_was_just_git_init_bare"`  (to remove)
