Mainly I'm working on the german Wikipedia. Due to my global account there is space for a page here - so I fill it with these lines...

$$ j^\mu = \sum_{i=1}^N \frac{\delta\mathcal{L}}{\delta(\partial_\mu\phi_i)}\varphi_i \quad,\quad \varphi_i := \left.\frac{\partial\phi_i}{\partial\alpha}\right|_{\alpha=0} $$

(BTW: This Noether current fulfills the Continuity equation :-)

For further details look at my page in german.
