+Install
+-------
+
+``pytexit`` is on PyPi::
+
+    pip install pytexit
+
+	
+Use
+---
+
+``pytexit`` features the ``py2tex``, ``for2tex`` ``for2py`` functions.
+
+In a Terminal, use ``py2tex``::
+
+    py2tex 'x = 2*sqrt(2*pi*k*T_e/m_e)*(DeltaE/(k*T_e))**2*a_0**2'
+
+In a Python console, use ``py2tex``::
+
+    from pytexit import py2tex
+    py2tex('x = 2*sqrt(2*pi*k*T_e/m_e)*(DeltaE/(k*T_e))**2*a_0**2')
+
+returns the corresponding LaTeX formula (to re-use in papers)::
+
+    $$x=2\\sqrt{\\frac{2\\pi k T_e}{m_e}} \\left(\\frac{\\Delta E}{k T_e}\\right)^2 a_0^2$$
+    
+and (in ipython console only) prints the equation:
