-# A synchronous and simple Maelstrom crate
-
-`nebkor-maelstreom` is a lean and simple synchronous library for writing
-[Maelstrom](https://github.com/jepsen-io/maelstrom/tree/0186f398f96564a0453dda97c07daeac67c3d8d7)-compatible
-distributed actors. It has three dependencies:
-
- - serde
- - serde_json
- - serde_repr
- 
-For a simple example, see the [gg-echo](https://git.kittencollective.com/nebkor/chatty-catties/src/branch/main/gg-echo/src/main.rs) program:
-
-``` rust
-use nebkor_maelstrom::{Body, Message, Node, Runner};
-
-struct Echo;
-
-impl Node for Echo {
-    fn handle(&mut self, runner: &Runner, msg: Message) {
-        let typ = &msg.body.typ;
-        if typ.as_str() == "echo" {
-            let body = Body::from_type("echo_ok").with_payload(msg.body.payload.clone());
-            runner.reply(&msg, body);
-        }
-    }
-}
-
-fn main() {
-    let node = Echo;
-
-    let runner = Runner::new(node);
-
-    runner.run(None);
-}
-```
-
-## How to use
-
-Create a struct and implement `nebkor_maelstrom::Node` for it, which involves a single method,
-`handle(&mut self, &Runner, Message)`. This method is passed a `Runner` which contains methods like
-`send`, `reply`, and `rpc`.
-
-In your main function, instantiate that struct and pass that into `Runner::new()` to get a
-Runner. The `run()` method takes an optional closure that will be run when the `init` Message is
-received; see the
-[broadcast](https://git.kittencollective.com/nebkor/chatty-catties/src/commit/fff7fdc2d52f7d4c2d4d9c581ea16cdf0e1e3f30/gg-broadcast/src/main.rs#L18-L33)
-program for an example of that, where it spawns a thread to send periodic messages to the node.
-
-## Design considerations
-
-I wanted the client code to be as simple as possible, with the least amount of boilerplate. Using
-`&mut self` as the receiver for the `handle()` method lets you easily mutate state in your node if
-you need to, without the ceremony of `Rc<Mutex<>>` and the like. Eschewing `async` results in an
-order of magnitude fewer dependencies, and the entire workspace (crate and clients) can be compiled
-in a couple seconds.
-
-## Acknowledgments
-
-I straight-up stole the design of the IO/network system from
-[Maelbreaker](https://github.com/rafibayer/maelbreaker/), which allowed me to get a working RPC
-call. Thanks!
-
-
-## TODO
-
- - add error handling.
