+# SpiX 🦜 Yet another TeX compilation tool: simple, human readable, no option, no magic
+
+SpiX is [yet another compilation tool](https://www.ctan.org/topic/compilation) for ``.tex`` files. It aims at being simple and human readable. Every piece of configuration is written in the ``.tex`` file itself, in a clear format (a list of console commands).
+
+## Why SpiX?
+
+With SpiX, the compilation process of a ``.tex`` file (Is it compiled using latex? pdflatex? xelatex? lualatex? Should I process its bibliography? with bibtex or biber? Is there an index?) is written in the ``.tex`` file itself, in a human-readable format (a shell script). That way:
+
+- when you want to compile two years later, you don't have to guess the compilation process;
+- you can send the ``.tex`` file to someone, and that's it: no need to send detailed instructions or a Makefile along with it (everything is in the ``.tex`` file);
+- the compilation process is human readable: it can be understood by anyone who is able to read a very basic shell script. In particular, one can read it even if she does not know SpiX.
+
+### The ``.tex`` file
+
+Write the compilation process of your ``.tex`` file as a shell script, before the preamble, as lines starting with ``%$``:
+
+    % Compile this file twice with lualatex.
+    %$ lualatex foo.tex
+    %$ lualatex foo.tex
+ 
+    \documentclass{article}
+    \begin{document}
+    Hello, world!
+    \end{document}
+
+You can also replace the file name with ``$texname``. That way, you don't have to worry about the file name when writing your commands.
+
+    % Compile this file twice with lualatex.
+    %$ lualatex $texname
+    %$ lualatex $texname
+
+### Compilation
+
+To compile the ``.tex`` file, run SpiX:
+
+    spix foo.tex
+
+Spix will parse the ``.tex`` file, looking for shell snippets (lines before the preamble starting with ``%$``), and run them.
+
+That's all!
+
+## Documentation

+The complete documentation is available on [readthedocs](http://spix.readthedocs.io).

+
+## What's new?
+
+See [changelog](https://framagit.org/spalax/spix/blob/master/CHANGELOG.md).
+
+## Download and install
+
+The preferred way to install SpiX used pip:
+
+    python3 -m pip install spix
+
+Other installation methods can be found in the [documentation](https://spix.readthedocs.io/en/latest/install/).
