The windows 10 version 1803 has contained an internal OpenSSH, so could the page [GitLab and SSH keys](https://docs.gitlab.com/ee/ssh/) be simplified for using OpenSSH to generate SSH key? Because this OpenSSH is default disable, ref [MSDN OpenSSH key management](https://docs.microsoft.com/en-us/windows-server/administration/openssh/openssh_keymanagement), so need a PowerShell running as administrator to execute `Get-Service ssh-agent | Set-Service -StartupType Manual` My experience for doing ssh-add is similar with the page's description but must run `Start-Service ssh-agent` first. The section "Use SSH on Microsoft Windows" should be put in "Prerequisites". Although it's good to know PuTTYGen can try when ssh-keygen and ssh -T are doing failure. But it's frustrated because it's GUI and don't use above command lines. It's not easy to troubleshoot any problem from different setting steps. <!-- Don't edit below this line -->
