installation doc

[ptoche]

first time here, followed the installation instruction, got the following error:

    mkdir ets
    cd ets
    git clone [email protected]:enthought/ets.git
    Cloning into 'ets'...
    Permission denied (publickey).
    fatal: Could not read from remote repository.
    Please make sure you have the correct access rights
    and the repository exists.

The following appeared to work.

    git clone https://github.com/enthought/ets.git

Would that be an acceptable way to proceed? Thanks.
