  - .ssh: 700
  - autherized_keys: 600
Verify the result

Launch the Git package. Select users to provide them with the ability to check in and check out files from the repository.
- If the panel is blank, try following
  - sudo vi /var/packages/Git/target/webapi/SYNO.Git.lib
  - delete the content within appPriv: -> “appPriv”: “”
Log into your Synology server via SSH as root or admin.
Change directory to /volumeX, where X is the volume number, to create a folder. For example, “git_repos”. The permission of the folder will be the same as Linux.
- You can also do it in web console
In the folder, run git init to create an empty repository.
- git init --bare <repo.git>
After the repository is created, a Git client user can enter the following command to access this repository:
- git clone ssh://[Git users]@[Your Synology server's IP address or hostname]/[Git repository path]
  - git clone ssh://user@nas.local/volume1/git/test1.git
  - ensure it starts from ssh://
  - You can also use the scp like style git clone [git_user]@nas.local:/volume1/git/helloworld.git
  - If you are using a port other than 22, update following
    - vi ~/.ssh/config
    Host nas.local Port 1234
