When I connect to source tree I can see my remote repository and the clone link to the side of it, these are the steps I am doing.
1. click on the clone link by the repository that I want
2. Am taken to the Clone screen and the repository is shown and the message is shown on the top that says Cloning is even easier if you set up a remote account
the clone button is shown on the bottom but greyed out,
There is a details button which when I click on it come up with an empty dialogue box
There is an Advance options at the bottom with the message Advanced options will appear once the repository type of the clone source has been detected successfully
