latex support, similar to gitbook-editor?

Hi, trying out this container with a gitbook i wrote in gitbook-editor - the math notation did not render, for example:

```
$$\delta^hj = \sum{W{jk}\delta^o_l f`(h_j)}$$
```

Not quite sure how hard it is to add something or whether plugins are available, please let me know if this needs custom coding or you need more info

BR,
