+# What is it?
+
+Brachylog is a declarative logic programming language much like Prolog. Brachylog is designed to be much terser than Prolog, while retaining some readability.
+
+Currently in development.
+
+Brachylog uses [SWI-Prolog](http://www.swi-prolog.org/) as Prolog engine.
+
+## How do I use this?
+
+### Documentation
+
+Check out [Brachylog's Wiki](https://github.com/JCumin/Brachylog/wiki) if you want to learn how to write programs in this language.
+
+You may want to watch this [**short video introduction to Brachylog**](https://www.youtube.com/watch?v=XYVhZ-MFcUs).
+
+### Try it online!
+
+You can try out Brachylog on [Try it online!](https://tio.run/nexus/brachylog2), thanks to @DennisMitchell.
+
+### Brachylog language bar
+
+[You can find here](https://abrudz.github.io/lb/brachylog) the Brachylog language bar which gives you access to all symbols used in Brachylog on any webpage (by clicking on the symbols or by inputing shortcuts), thanks to @abrudz.
+
+### The interpreter
+
+Brachylog's interpreter is entirely written in Prolog. Therefore, installing [SWI-Prolog](http://www.swi-prolog.org/) (version 7 and up) is mandatory to use Brachylog (We do not guarantee that Brachylog's interpreter will be compatible with any other Prolog implementation).
+
+To run Brachylog's interpreter, start SWI-Prolog's interpreter inside the `src` directory available in this repository, and consult the file `brachylog.pl` (`consult(brachylog).`). Alternatively, you can run the interpreter with:
+
+    $ swipl src/brachylog.pl
+
+You can then run Brachylog programs using different predicates:
+
+ - `run_from_file(FileName, Input, Output)`: `FileName` is an atom (i.e. between single quotes `'`) representing the file containing your Brachylog code. For example: `run_from_file('code.brachylog',"Test Input",Z)`.
+ 
+ - `run_from_atom(Code, Input, Output)`: `Code` is an atom (i.e. between single quotes `'`) containing your Brachylog code. For example: `run_from_atom('∧"Hello, World!"w',_,_)`. Note that you will have to escape certain characters in `Code`.
+
+ - `run(Input, Output)`: This will run a Brachylog program that has already been transpiled to Prolog using either of the two previous predicates. More precisely, this will query `brachylog_main/2` in the file `compiled_brachylog.pl`.
+
+The first two predicates will transpile your Brachylog program into Prolog, subsequently generating a file called `compiled_brachylog.pl` in the same directory that contains `brachylog.pl`. The three run predicates will then consult it and query `brachylog_main/3`.
+ 
+Note that the first two run predicates also exist with either no `Output` argument, or with no `Input` nor `Output` argument, if necessary. For example, `run_from_file('code.brachylog')` is equivalent to `run_from_file('code.brachylog', _, _)`.
