+# Rock {version}
+
+[![Rust](https://github.com/Champii/Rock/actions/workflows/rust.yml/badge.svg?branch={branch})](https://github.com/Champii/Rock/actions/workflows/rust.yml)
+
+Little toy language made with Rust and LLVM.  
+Aim to follow the Rust model with enforced safeness with a borrow checker and native performances thanks to LLVM.  
+It's highly inspired from Livescript, and will borrow (pun intended) some features and syntaxes from Crystal, from functional languages like Haskell, or even from Rust itself.

+## Features
+
+- Strongly typed
+- Type inference
+- Custom operators
+- Typeclass (Traits)
+- Parametric Polymorphism by default
+- Compile to LLVM IR
+
+## Development notes
+
+This project, its syntax and its APIs are subject to change at any moment.  
+This is a personal project, so please bear with me  
+(Differently put: this is a big red hot pile of experimental garbage right now)
+
+## Install
+
+How to install and run the compiler:
+
+### Using released binary
+
+[Rock {version}](https://github.com/Champii/Rock/releases/download/{version}}/rock) (Tested on arch linux)
+
+``` sh
+wget https://github.com/Champii/Rock/releases/download/{version}/rock
+chmod +x rock
+./rock -V
+```
+
+### With cargo from git
+
+``` sh
+cargo install --git https://github.com/Champii/Rock
+rock -V
+```
+
+### From sources
+
+``` sh
+git clone https://github.com/Champii/Rock.git
+cd Rock
+cargo run -- -V
+```
+
+## Quickstart
+
+Lets create a new project folder to compute some factorials
+
+``` sh
+mkdir -P factorial/src && cd factorial
+```
+
+Add some files like this:
+
+- Copy the std lib files from [std](https://github.com/Champii/Rock/blob/master/std/src) into `./src/`
+
+- Create a `./src/main.rk` file:
+
+```haskell
+mod lib
+
+use lib::prelude::*
+
+# Polymophic function
+id a = a
+
+fact a =
+    if a <= 1
+    then 1
+    else a * fact (a - 1)
+
+main = print fact id 4
+```
+
+Assuming that you built Rock and put its binary in your PATH:
+
+``` sh
+rock run
+```
+
+Should output
+
+``` sh
+24
+```
+
