I am trying to use the Community Store. The store works brilliantly (excellent job - thanks!) but I cannot install the PayPal Standard gateway which is going to be esential.

I downloaded community_store_paypal_standard-master unzip from github and put it in the packages folder. Is this right?

Under Awaiting installation I get Cant Install!
Unknown Package v.0.0
Broken package (handle community_store_paypal_standard-master).

...although the PayPal icon is there so its found that at least.
Can someone please help?
