Git Clone can only be invoked by those who are members of a repository. It will ask you for the git address (It will start with git@… ) Get that address from the owner of the repository. Cloning can only be done on the Work folder you had setup or one of the suitable sub-folders beneath that in the folder-tree.
For Git Clone to work, your private key must be available in the members sub-folder (inside the application folder) and the name of that file should be as explained below:
<reposname>_<membername>.priv
The above is the format of the file. In the above, replace <reposname> with the name of the repository being cloned. And <membername> is your name (i.e. the member who is allowd to clone)
For example; if the name of the repository is office_graphics and your name is Alpha then the filename inside the members sub-folder would be:
office_graphics_Alpha.priv
There should NOT be any spelling mistake in the above filename. And the contents of the filename must be the private SSH key that was assigned to that member. Before the cloning action was done, the owner of the repository should have added that member and setup the keys for that member. So here, it is assumed that such a member already has the private key.
