One feature of Discourse is writing code in Julia:

```auto
a = zeros(N)
b = [j for j=1:N]
function f(N::Int)
  for i=1:N
    println(i)
  end
end

```

or in C++:

```auto
int main()
{
auto N = 10;
}

```

Another feature is math notation with \LaTeX such as

i \frac{\partial \Psi}{\partial t} = \hat{H} \Psi
