Get it done

I tried hexo on Github Pages for fun,
but don’t know why I should use it.
I may not post on this site much.
Test equations:
For any $x > 0$, $y> 0$,
$$G(x) = \int_0^x e^{-\frac{x^2}{2}} \mathrm{d}x.$$

Other examples:

$$\begin{aligned} \dot{x} & = \sigma(y-x) \\ \dot{y} & = \rho x - y - xz \\ \dot{z} & = -\beta z + xy \end{aligned}$$

The local website updates right after saving the md file, that’s nice.
After installing hexo-livereload plugin, the browser will automatically refresh as well!
