+Pytex is a simple package which make a bridge between Latex and Python.
+
+## Installation
+
+``` bash
+pip install mypytex
+```
+
+## texenv: Bring Python inside latex
+
+*texenv* is a jinja2 environment which allow to use python commands inside latex.
+
+- **\Block{#}**  is the equivalent of **{% block #%}** in Jinja2. Every python's commands will be run like in a script. **%-** is also available for line statement.
+- **\Var{#}** is the equivalent of **{{#}}** which print the statment.
+
+Use the environment with a string template.
+
+``` python
+>>> from pytex import texenv
+
+>>> text = "Hello"
+>>> template = """\
+\Var{text}
+\Block{set a = 2}
+%-set b = 3
+\Var{a}
+\Var{b}
+"""
+
+>>> template = texenv.from_string(template)
+>>> print(template.render(text = text)
+Hello
+
+2
+3
+
+
+```

+## feed: converting template into tex files
+
+## pdflatex: Compile files with pdflatex
