How can I move one of the 3 free sites to local development with shipper?

Hi,

How can I move the above listed site to local development with shipper?

I want to develop it offline and then upload/deploy it to another host.

I feel it is going a little slow on the free hosting at the moment and the header collapses and things get compressed in a weird way periodically.

So I thought local development might be a good idea.

Thanks

Mike
