Stash setup
Ensure user has an account and password for Stash. If no userid, go to www.ecmwf.int/login and register. I then need to add this new user to the repository if they are outside ECMWF
Then go to - https://software.ecmwf.int/stash/login. If user has not yet set a password, click on the "Can't access your account?" link which will send them an email describing how to reset the password.
Once password is set, make sure userid and password work ok and the user can login to stash and see the OpenIFS git repository.
Cloning
To clone the repository at the remote site (once above login is successful):
mkdir ecmwf cd ecmwf git clone https://nagc@software.ecmwf.int/stash/scm/oifs/openifs.git
This will create a directory 'openifs' in 'ecmwf'.
That's it!
