 + A Lithium app
++ You don't have Lithium core library as a submodule in your application `libraries` folder, as you don't want to clone Lithium core each time you deploy your app (a couple time a day if you are as cool as Lithium!).

 + Must have SSH access to the server you are deploying to.
 + You either have the same password to all target machines, or you have public keys in place to allow passwordless access to them.
