 Eagle is a library which allows you to easily build an [RPC](https://en.wikipedia.org/wiki/Remote_procedure_call) protocol.
 It uses a macro to generate the required communication code and makes adding new functions easy and quick. Eagle is designed to work specifically with [`tokio`](https://crates.io/crates/tokio) and uses [`serde`](https://crates.io/crates/serde) for formatting data.
 
+Please note that since `eagle` is a pure proc-macro library, you must manually add compatible versions of `tokio`, `serde`, `ron` and optionally `log` to your dependencies.
+
 ## Using Eagle
 
 The way that `eagle` is designed to be used is inside a shared dependency between your "server" and your "client". Both of these should be in a workspace. Create a `shared` crate which both components should depend on, this crate should have `eagle` as a dependency. By default `eagle` uses TCP for communication, but you may disable default features and enable the `unix` feature on `eagle` to use unix sockets instead.
