+## What?
+
+
+Naylang is the new interpreter, runtime and debugger for a subset of the [Grace Programming Language](http://gracelang.org/applications/).
+It's still a work in progress, but it has some great features already!
+
+## How?
+
+To use Naylang, just download the executable for the [latest release](https://github.com/blorente/naylang/releases) and start it up in a terminal!
+
+If you'd rather compile it from source [click me!](#compilation-instructions)
+
+
+
+### Commands
+
+For now, Naylang accepts three kinds of commands:
+
+
+- `load` (or `l`) `<path>`: Open the file in `<path>`, execute it, and show the resulting environment.
+
+- `exec `(or `e`) `<code>`: Execute the code and show the resulting environment.
+
+- `print` (or `p`) `<expression>`: Execute the expression and show the result.
+
+
+
+Here's an example execution of Naylang:

+
+
+
+## Want to contribute?
+
+
+
+Naylang is written entirely in modern C++14. 
+It uses [ANTLR4](https://antlr.org) for parsing, [CMake](https://cmake.org/)
+ as a build system and [Catch](https://github.com/philsquared/Catch) as a testing framework.
+
+ 
+If you'd like to contribute to this project, you are more than welcome to. 
+Feel free to [submit an issue](https://github.com/blorente/naylang/issues/new),
+ 
+fork the [main repo](https://github.com/blorente/naylang) and submit a pull request with your improvements, 
+or even shoot me an email (blorente@ucm.es) if you want some direction on where to begin.
+
+
+
+### Compilation instructions
+
+
+Naylang uses standard out-of-source compilation with CMake. 
+It requires at least version 3 of CMake and a compiler that supports C++14 (for example, GCC6.x). 
+
+
+
+When all those dependencies are installed, just download the repo (`git clone https://github.com/blorente/naylang`) and
+a simple sequence of commands should suffice to run the tests:
+
+
+
+```
+
+cd /root/of/repo
+mkdir
+build &6 cd build
+
+cmake ..
+
+make -j antlr4cpp antlr4cpp_generation_naylang
+
+cmake ..
+
+make -j
+
+cd tests
+
+chmod +x ./tests
+
+./tests
+
+```
