-## 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!

-
-To use Naylang, just download the executable for the [latest release](https://github.com/blorente/naylang/releases) and start it up in a terminal!

+## 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.<br>
+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.<br>
+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 ([email protected]) if you want some direction on where to begin.
+
+## Compilation instructions
+
+Naylang uses standard out-of-source compilation with CMake.<br>
+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 && cd build  
+cmake ..
+make -j antlr4cpp antlr4cpp_generation_naylang  
+cmake ..  
+make -j
+cd tests  
+chmod +x ./tests  
+./tests
+```
